The Great Depression began in August 1929, when the United States economy first went into an economic recession. Although the country spent two months with declining GDP, it was not until the Wall Street Crash in October 1929 that the effects of a declining economy were felt, and a major worldwide economic downturn ensued. The market crash marked the beginning of a decade of high unemployment, poverty, low profits, deflation, plunging farm incomes, and lost opportunities for economic growth and personal advancement. Although its causes are still uncertain and controversial, the net effect was a sudden and general loss of confidence in the economic future. 
The usual explanations include numerous factors, especially high consumer debt, ill-regulated markets that permitted overoptimistic loans by banks and investors, and the lack of high-growth new industries, all interacting to create a downward economic spiral of reduced spending, falling confidence and lowered production.
Industries that suffered the most included construction, agriculture as dust-bowl conditions persisted in the agricultural heartland, shipping, mining, and logging as well as durable goods like automobiles and appliances that could be postponed. The economy reached bottom in the winter of 1932-33; then came four years of very rapid growth until 1937, when the Recession of 1937 brought back 1934 levels of unemployment.
The Depression caused major political changes in America. Three years into the depression, President Herbert Hoover, widely blamed for not doing enough to combat the crisis, lost the election of 1932 to Franklin Delano Roosevelt in a landslide. Roosevelt's economic recovery plan, the New Deal, instituted unprecedented programs for relief, recovery and reform, and brought about a major realignment of American politics.
The Depression also resulted in an increase of emigration of people for the first time in American history. For example, some immigrants went back to their native countries, and some native US citizens went to Canada, Australia, and South Africa. It also resulted in the mass migration of people from badly hit areas in the Great Plains and the South to places such as California and the North, respectively (see Okies and the Great Migration of African Americans). Racial tensions also increased during this time. By the 1940s immigration had returned to normal, and emigration declined. A well-known example of an emigrant was Frank McCourt, who went to Ireland, as recounted in his book Angela's Ashes.
The memory of the Depression also shaped modern theories of economics and resulted in many changes in how the government dealt with economic downturns, such as the use of stimulus packages, Keynesian economics, and Social Security. It also shaped modern American literature, resulting in famous novels such as John Steinbeck's The Grapes of Wrath and Of Mice and Men.
There are multiple originating issues: what factors set off the first downturn in 1929, what structural weaknesses and specific events turned it into a major depression, how the downturn spread from country to country, and why the economic recovery was so prolonged.
Banks began to fail in October 1930 (one year after the crash) when farmers defaulted on loans. There was no federal deposit insurance during that time as bank failures were considered quite common. This worried depositors that they might have a chance of losing all their savings, therefore, people started to withdraw money and changed it into currency. As deposits taken out from the bank increased, the money supply decreased because the money multiplier worked in reverse, forcing banks to liquidate assets (such as call in loans rather than create new loans.) This caused the money supply to shrink and the economy to contract and a significant decrease in aggregate investment. The decreased money supply further aggravated price deflation, putting further pressure on already struggling businesses.
The US government's commitment to the gold standard prevented it from engaging in expansionary monetary policy.[clarification needed] High interest rates needed to be maintained, in order to attract international investors who bought foreign assets with gold. However, the high interest also inhibited domestic business borrowing. The US interest rates were also affected by France's decision to raise their interest rates to attract gold to their vaults. In theory, the U.S. would have two potential responses to that: Allow the exchange rate to adjust, or increase their own interest rates to maintain the gold standard. At the time, the U.S. was pegged to the gold standard. Therefore, Americans converted their dollars into francs to buy more French assets, the demand for the U.S. dollar fell, and the exchange rate increased. The only thing the US could do to get back into equilibrium was increase interest rates.
The Stock Market Crash of 1929 is often cited as the beginning of the Great Depression. It began on October 24, 1929, and was the most devastating stock market crash in the history of the United States. A lot of the stock market crash can be blamed on over exuberance and false expectations. In the years leading up to 1929, the stock market offered the potential for making huge gains in wealth. As share prices rose, people started to borrow money to invest in the stock market. However, on October 24 (Black Thursday), share prices began to fall and panic selling caused prices to fall sharply. On October 29 (Black Tuesday), share prices fell by $14 billion in a single day, more than $30 billion in the week.  The value that evaporated the week was 10x more than the entire federal budget and more than all of what the U.S. spent on World War I. By 1930 the value of shares had fallen by 90%. 
Since many banks had also invested their clients' savings in the stock market, these banks were forced to close when the stock market crashed. After the stock market crash and the bank closures, people were too afraid to lose more money. Because of the fears of further economic challenge, individuals from all classes stopped purchasing and consuming. Thousands of individual investors who believed they could get rich by investing on margin lost everything they had. The stock market crash severely impacted American economy.
A large contribution to the recession is due to the closure and suspension of thousands of banks across the country. The causation of these failing financial institutions come from several reasons including unregulated lending procedures, confidence in the Gold standard, consumer confidence in future economics, and agricultural defaults on outstanding loans. With these compacting issues the banking system struggled to keep up with the high demand of cash withdraws from the public. This impact overall decreased the money supply and forced the banks to result to short sale (real estate) and liquidation of existing loans. In the race to liquidate assets the banking system began to fail on a wide scale. In November 1930 the first major banking crisis begun with over 800 banks closing their doors by January 1931; over 2100 banks will be suspended by October 1931, with the highest suspension rate recorded in the St. Louis Federal Reserve District with 2 out of every 5 banks suspended. The economy in whole experienced a massive reduction in banking footholds across the country amounting to more than nine thousand closed banks by 1933.
The closures resulted in a massive withdraw of deposits by millions of Americans estimated near 6.8 billion dollars (equivalent to around 60 billion dollars in today's dollars). During this time the Federal Deposit Insurance Corporation (FDIC) was not in place resulting in a loss of roughly 1.36 billion dollars (or 20%) of the total 6.8 billion accounted for within the failed banks. These losses will come directly from everyday individuals savings, investments, and daily banking accounts. GDP will fall as a result from the high seven-hundreds in 1929 to the low mid six-hundreds in 1933 before seeing any recovery for the first time in nearly 4 years. Federal leadership intervention is highly debated on its effectiveness and overall participation. The Federal Reserve Act could not effectively tackle the banking crisis as state bank and trust companies were not compelled to be a member, paper eligible discount member banks heavily restricted access to the fed, power between the twelve federal reserve banks was decentralized and federal level leadership were ineffective, inexperienced, and weak.
Throughout the early 1900s banking regulations were extremely lax if not non-existent. The Currency Act of 1900 lowered the required Capital (economics)of investors from 50,000 to 25,000 to create a national bank. As a result of this change nearly two thirds of the banks formed over the next ten years were quite small, averaging just above the 25,000 in required capital. The number of banks will nearly double (number of banks divided by Real GDP) from 1890 to 1920 due to the lack of oversight and qualification when banking charters were being issued in the first two decades of the 1900s.
The unregulated growth of small rural banking institutions can be partially attributed to the rising cost of agriculture especially in the Corn Belt and Cotton Belt. Throughout the corn and cotton belts real estate increases drove the demand for more local funding to continue to supply rising agricultural economics. The rural banking structures would supply the needed capital to meet the farm commodity market, however, this came with a price of reliability and low risk lending. Economic growth was promising during the period of 1887-1920 with an on average of 6 percent growth in [GDP]. In particular the participation in World War I (1917-1918) drove a booming agricultural market that drove optimism at the consumer and lending level, which in turn, resulted in a laxer approach in the lending process. Overbanked conditions existed which pressured struggling banking locations to increase their services (specifically to the agricultural customers) without any additional regulatory oversight or qualifications. This dilemma introduced several high risk and marginal business returns to the banking market. Banking growth would continue through the first two decades well outside of previous trends disregarding the current economic and population standards. Banking profitability and loan standards begin to deteriorate as early as 1900 as a result; adding to the agriculture shock and Great Depression to follow.
Crop failures beginning in 1921 began to impact this poorly regulated system, the expansion areas of corn and cotton suffered the largest due to the dust bowl era resulting in real estate value reductions. In addition, the year 1921 was the peak for banking expansion with roughly 31,000 banks in activity, however, with the failures at the agricultural level 505 banks would close between 1921 -1930 marking the largest banking system failure on record. Regulatory questions began to hit the debating table around banking qualifications as a result; discussions would continue into the [Great Depression] as not only were banks failing but some would disappear altogether with no rhyme or reason. The panic of financial crisis would increase in the Great Depression due to the lack of confidence in the regulatory and recovery displayed during the 1920s, this ultimately drove a nation of doubts, uneasiness, and lack of consumer confidence in the banking system.
With a lack of consumer confidence in the economic direction given by the federal government panic started to spread across the country shortly after the Wall Street Crash of 1929. President Hoover retained the Gold Standard as the country's currency gauge throughout the following years. As a result, the American shareholders with the majority of the gold reserves began to grow wary of the value of gold in the near future. Europe's decision to move away from the Gold Standard caused individuals to start to withdraw gold shares and move the investments out of the country or began to horde gold for future investment. The market continued to suffer due to these reactions, and in result caused several of the everyday individuals to speculate on the economy in the coming months. Rumors of market stability and banking conditions began to spread, consumer confidence continued to drop and panic begin to set in. Contagion spread like wild fire pushing Americans all over the country to withdraw their deposits in mass. This idea would continue from 1929-1933 causing the greatest financial crisis ever seen at the banking level pushing the economic recovery efforts further from resolution. An increase in the currency-deposit ratio and a money stock determinant forced money stock to fall and income to decline. This panic-induced banking failure took a mild recession to a major recession.
Whether this caused the Great Depression is still heavily debated due to many other attributing factors. However, it is evident that the banking system suffered massive reductions across the country due to the lack of consumer confidence. As withdraw requests would exceed cash availability banks began conducting steed discount sales such as fire sales and short sales. Due to the inability to immediately determine current value worth these fire sales and short sales would result in massive losses when recuperating any possible revenue for outstanding and defaulted loans. This would allow healthy banks to take advantage of the struggling units forcing additional losses resulting in banks not being able to deliver on depositor demands and creating a failing cycle that would become wide spread. Investment would continue to stay low through the next half decade as the private sector would horde savings due to uncertainty of the future. The federal government would run additional policy changes such as the Check tax, monetary restrictions (including reduction of money supply by burning), High Wage Policy, and The New Deal through the Hoover and Roosevelt administration.
One visible effect of the depression was the advent of Hoovervilles, which were ramshackle assemblages on vacant lots of cardboard boxes, tents, and small rickety wooden sheds built by homeless people. Residents lived in the shacks and begged for food or went to soup kitchens.The term was coined by Charles Michelson, publicity chief of the Democratic National Committee, who referred sardonically to President Herbert Hoover whose policies he blamed for the depression.
Unemployment reached 25 percent in the worst days of 1932-33, but it was unevenly distributed. Job losses were less severe among women, workers in nondurable industries (such as food and clothing), services and sales workers, and those employed by the government. Unskilled inner city men had much higher unemployment rates. Age also played a factor: young people had a hard time getting their first job, and men over the age of 45, if they lost their job, would rarely find another one because employers had their choice of younger men. Millions were hired in the Great Depression, but men with weaker credentials were never hired, and fell into a long-term unemployment trap. The migration that brought millions of farmers and townspeople to the bigger cities in the 1920s suddenly reversed itself, as unemployment made the cities unattractive, and the network of kinfolk and more ample food supplies made it wise for many to go back. City governments in 1930-31 tried to meet the depression by expanding public works projects, as president Herbert Hoover strongly encouraged. However, tax revenues were plunging, and the cities as well as private relief agencies were totally overwhelmed by 1931; no one was able to provide significant additional relief. People fell back on the cheapest possible relief, soup kitchens which provided free meals for anyone who showed up. After 1933 new sales taxes and infusions of federal money helped relieve the fiscal distress of the cities, but the budgets did not fully recover until 1941.
The federal programs launched by Hoover and greatly expanded by President Roosevelt's New Deal used massive construction projects to try to jump start the economy and solve the unemployment crisis. The alphabet agencies ERA, CCC, FERA, WPA and PWA built and repaired the public infrastructure in dramatic fashion, but did little to foster the recovery of the private sector. FERA, CCC and especially WPA focused on providing unskilled jobs for long-term unemployed men.
The Democrats won easy landslide victories in 1932 and 1934, and an even bigger one in 1936; the hapless Republican Party seemed doomed. The Democrats capitalized on the magnetic appeal of Roosevelt to urban America. The key groups were low skilled ethnics, especially Catholic, Jewish, and black people. The Democrats promised and delivered in terms of political recognition, labor union membership, and relief jobs. The cities' political machines were stronger than ever, for they mobilized their precinct workers to help families who needed help the most navigate the bureaucracy and get on relief. FDR won the vote of practically every demographic in 1936, including taxpayers, small business and the middle class. However, the Protestant middle class voters turned sharply against him after the recession of 1937-38 undermined repeated promises that recovery was at hand. Historically, local political machines were primarily interested in controlling their wards and citywide elections; the smaller the turnout on election day, the easier it was to control the system. However, for Roosevelt to win the presidency in 1936 and 1940, he needed to carry the electoral college and that meant he needed the largest possible majorities in the cities to overwhelm rural voters. The machines came through for him. The 3.5 million voters on relief payrolls during the 1936 election cast 82% percent of their ballots for Roosevelt. The rapidly growing, energetic labor unions, chiefly based in the cities, turned out 80% for FDR, as did Irish, Italian and Jewish communities. In all, the nation's 106 cities over 100,000 population voted 70% for FDR in 1936, compared to his 59% elsewhere. Roosevelt worked very well with the big city machines, with the one exception of his old nemesis, Tammany Hall in Manhattan. There he supported the complicated coalition built around the nominal Republican Fiorello La Guardia, and based on Jewish and Italian voters mobilized by labor unions.
In 1938, the Republicans made an unexpected comeback, and Roosevelt's efforts to purge the Democratic Party of his political opponents backfired badly. The conservative coalition of Northern Republicans and Southern Democrats took control of Congress, outvoted the urban liberals, and halted the expansion of New Deal ideas. Roosevelt survived in 1940 thanks to his margin in the Solid South and in the cities. In the North the cities over 100,000 gave Roosevelt 60% of their votes, while the rest of the North favored Willkie 52%-48%.
With the start of full-scale war mobilization in the summer of 1940, the economies of the cities rebounded. Even before Pearl Harbor, Washington pumped massive investments into new factories and funded round-the-clock munitions production, guaranteeing a job to anyone who showed up at the factory gate. The war brought a restoration of prosperity and hopeful expectations for the future across the nation. It had the greatest impact on the cities of the West Coast, especially Los Angeles, San Diego, San Francisco, Portland and Seattle.
Economic historians led by Price Fishback have examined the impact of New Deal spending on improving health conditions in the 114 largest cities, 1929-1937. They estimated that every additional $153,000 in relief spending (in 1935 dollars, or $1.95 million in year 2000 dollars) was associated with a reduction of one infant death, one suicide, and 2.4 deaths from infectious disease. 
The Great Depression began in the United States of America and quickly spread worldwide. It had severe effects in countries both rich and poor. Personal income, consumption, industrial output, tax revenue, profits and prices dropped, while international trade plunged by more than 50%. Unemployment in the U.S. rose to 25%, and in some countries rose as high as 33%.
Cities all around the world were hit hard, especially those dependent on heavy industry. Construction was virtually halted in many countries. Farming and rural areas suffered as crop prices fell by approximately 60%. Facing plummeting demand with few alternate sources of jobs, areas dependent on primary sector industries such as grain farming, mining and logging, as well as construction, suffered the most.
Most economies started to recover by 1933-34. However, in the U.S. and some others the negative economic impact often lasted until the beginning of World War II, when war industries stimulated recovery.
There is little agreement on what caused the Great Depression, and the topic has become highly politicized. At the time the great majority of economists around the world recommended the "orthodox" solution of cutting government spending and raising taxes. However, British economist John Maynard Keynes advocated large-scale government deficit spending to make up for the failure of private investment. No major nation adopted his policies in the 1930s.
The stock market crash in the 1929 not only affected the business community and the public's economic confidence, but also it led to the banking system soon after the turmoil. The boom of the US economy in the 1920s was based on high indebtedness, and the rupture of the debt chain caused by the collapse of the bank had produced widespread and far-reaching adverse effects. It is precisely because of the shaky banking system, the United States was using monetary policy to save the economy that had been severely constrained. The American economist Kindleberger of long-term studying of the Great Depression pointed out that in the 1929, before and after the collapse of the stock market, the Fed lowered interest rates, tried to expand the money supply and eased the financial market tensions for several times, however they were not successful, the fundamental reason was that the relationship between various credit institutions and the community was in a drastic adjustment process, the normal supply channels for money supply were blocked. Later, some economists argued that the Fed should do a large-scale opening market business at that time, but the essence of the statement was that the US government should be quick to implement measures to expand fiscal spending and fiscal deficits, whereas, the essence of this argument was that the US government should be promptly implemented to expand the fiscal spending and the fiscal deficits measures.
Between the 1920s and 1930s, The United States began to try the tight money policy to promote economic growth. In terms of the fiscal policy, the US government failed to reach a consensus on the fiscal issue. President Hoover began to expand federal spending, he set up a governmental financial revitalization company to provide emergency assistance to banks and financial institutions that were on the verge of bankruptcy. Hoover's fiscal policy had accelerated the recession. In December 1929, as means of showing government confidence of the economy, Hoover reduced all income tax rates by 1% of 1929 due to the continuing budget surplus. By 1930, the surplus turned into a fast-growing deficit of economic contraction. In 1931, the US federal fiscal revenue and expenditure changed from the financial surplus to deficit for the first time (the deficit was less than 2.8% of GDP). By the end of 1931, Hoover had decided to recommend a large increase in taxes to balance the budget; in addition, Congress approved the tax increase in 1932, a substantial reduction in personal immunity to increase the number of taxpayers, and the interest rates had risen sharply, the lowest marginal rate rose from 25% on taxable income in excess of $100,000 to 63% on taxable income in excess of $1 million as the rates were made much more progressive. Hoover changed his approach to fighting the Depression. He justified his call for more federal assistance by noting that "We used such emergency powers to win the war; we can use them to fight the Depression, the misery, and suffering from which are equally great." This new approach embraced a number of initiatives. Unfortunately for the President, none proved especially effective. Just as important, with the presidential election approaching, the political heat generated by the Great Depression and the failure of Hoover's policies grew only more withering.
In terms of the financial reform, since the recession, Hoover had been trying to repair the economy. He founded government agencies to encourage labor harmony and support local public works aid which promoted cooperation of government and business, stabilize prices, and strive to balance the budget. His work focused on indirect relief from individual countries and the private sector, which was reflected in the letter emphasizing "more effective supporting for each national committee" and volunteer service -" appealing for funding" from outside the government. The commitment to maintain the gold standard system prevented the Federal Reserve expanded its money supply operations in 1930 and 1931, and it promoted Hoover's destructive balancing budgetary action to avoid the gold standard system overwhelming the dollar. As the Great Depression became worse, the call raised for increasing in federal intervention and spending. But Hoover refused to allow the federal government to force fixed prices, control the value of the business or manipulate the currency, in contrast, he started to control the dollar price. For official dollar prices, he expanded the credit base through free market operations in federal reserve system to ensure the domestic value of the dollar. He also tended to provide indirect aid to banks or local public works projects, refused to use federal funds to give aid to citizens directly, which will reduce public morale. Instead, he focused on volunteering to raise money. Even though Hoover was a philanthropist before becoming president, his opponents regarded him as not responsible for the citizens. During the administration of Hoover, the US economic policies had moved to activism and interventionism. In his re-election campaign, Hoover tried to persuade the Americans to claim that the measures they requested seemed to be helpful in the short term, but it would be devastating in the long run. Eventually, he was defeated by Franklin Roosevelt in 1932.
At the beginning of 1933, the last few weeks of Hoover's term, the American financial system was paralyzed. The Great Depression was extended by the interventionist policy for four years. Bank crisis caused the serious deflationary pressures. For this phenomenon, Hoover still wanted to stop it. In fact, the worst period of 1932 - the Great Depression had passed, but the recovery was slow and weak. During the financial crisis of 1933 that culminated in the banking holiday in March 1933, a lot of gold flowed out from the Fed, some of them flow out to individuals and companies in the United States. This domestic loss occurred because individuals and businesses like to deposit metal gold into bank deposits or banknotes, some gold flows to foreign countries, and this external loss occurred because foreign investors were worried about the depreciation of the dollar.Roosevelt understands that the traditional political and financial policy cannot save the United States from the "disaster years", he pursued the "New Deal" to attempt to make up for the United States by administrative means. In the spring and summer of 1933, the Roosevelt government suspended the gold standard. The Emergency Banking Act gave the President the power to control international and domestic gold sports. It also gave the treasury secretary the power to surrender of gold coins and certificates. On April 20, President Roosevelt issued a formal announcement of the moratorium on the gold standard. The announcement prohibited gold exports, and prohibited financial institutions from converting money and deposits into gold coins and ingots. The action prevented the gold outflow. Soon, the Roosevelt government weakened the connection with gold once again. Thomas amendment to the Agricultural Relief Act to the gave to the President power to reduce the dollar's gold content by as much as 50%. The President Roosevelt also used the silver standard instead of gold to exchange dollars, it determined by the price of the bank. In April 1933, Roosevelt decided to abolish the gold standard through the New Deal. He abandoned this traditional monetary policy is mainly due to the big crisis to the original monetary policy failure. And the purpose of his action is to prohibit all exports of gold except for foreign countries, so that the United States can maintain an equal monetary base with the vast majority of countries. The Hoover government stubbornly insisted on using the "sound money" policy who against deficit spending and state relief that only make the economic crisis worsen. Because of this situation Roosevelt forced the implementation of inflation, and used the federal deficit spending to promote employment to enforce relief. The abandon of the gold standard made the Wall Street stock prices quickly increased, Wall Street's stock trading was exceptionally active, with a total of 5 million shares delivered on a day, which is the most active day in the past six months.
The Hoover Administration attempted to correct the economic situation quickly, but was unsuccessful. Throughout Hoover's presidency, businesses were encouraged to keep wage rates high. President Hoover and many academics believed that high wage rates would maintain a steady level of purchasing power, keeping the economy turning. In December 1929, after the beginning phases of the depression had begun, President Hoover continued to promote high wages. It wasn't until 1931 that business owners began reducing wages in order to stay afloat. Later that year, The Hoover Administration created the Check Tax to generate extra government funding. The tax added a two cent tax to the purchase of all bank checks, directly effecting the common person. This additional cost pushed people away from using checks, so instead the majority of the population increased their usage of cash. Banks had already closed due to cash shortage, but this reaction to the Check Tax rapidly increased the pace.
In the "First New Deal" of 1933-34, A wide variety of programs were targeted toward the depression and agriculture in rural areas, in the banking industry, and for the economy as a whole. Relief programs were set up for the long-term unemployed who are routinely passed over whenever new jobs did open up.  The most popular program was the Civilian Conservation Corps the put young men to work in construction jobs, especially in rural areas. Prohibition was repealed, the filling a campaign pledge and generating new tax revenues for local and state government. A series of relief programs were designed to provide jobs, in cooperation with local governments. The National Recovery Administration (NRA), sought to stimulate demand and provide work and relief through increased government spending. To end Deflation the Gold standard was suspended and a series of panels comprising business leaders in each industry set regulations which ended what was called "cut-throat competition," believed to be responsible for forcing down prices and profits nationwide. Several Hoover agencies were continued, most notably the Reconstruction Finance Corporation, which provided large-scale financial aid to banks, railroads, and other agencies. Reforms that had never been enacted in the 1920s now took center stage, such as the Tennessee Valley Authority (TVA) designed to electrify and modernize a very poor, mountainous region in Appalachia.
In 1934-36, came the much more controversial"Second New Deal." It featured social security; the Works Progress Administration (WPA), a Very large relief agency for the unemployed run by the federal government; the National Labor Relations Board, Which operated as a strong stimulus to the growth of labor unions. Unemployment fell by 2/3 in Roosevelt's first term (from 25% to 9%, 1933-1937). The second set of reforms launched by the Roosevelt Administration during the same period, which is a responsibility for social welfare with the main legislation ---- Social Security Act in 1935. Insurance and poor relief ("public assistance" or "welfare")are constituent parts of the legislation that provided pensions to the aged, benefit payments to dependent mothers, crippled children and blind people, and unemployment insurance. The Social Security Act still plays a significant role of the American health and human service system so far. Much of the economy had recovered by 1936, but persistent, long-term unemployment lasted until rearmament began for World War II in 1940.
The New Deal was, and still is, sharply debated. The business community, with considerable support from such conservative Democrats as Al Smith, Launched a crusade against the new deal, warning that dangerous man had seized control of the economy and threatened America's conservative traditions.  Scholars remain divided as well. When asked whether "as a whole, government policies of the New Deal served to lengthen and deepen the Great Depression," 74% of American university professors specializing in economic history disagreed, 21% agreed with provisos, and 6% fully agreed. Among respondents who taught or studied economic theory, 51% disagreed, 22% agreed with provisos, and 22% fully agreed. Robert Whaples, "Where Is There Consensus Among American Economic Historians?

By 1936, all the main economic indicators had regained the levels of the late 1920s, except for unemployment, which remained high. In 1937, the American economy unexpectedly fell, lasting through most of 1938. Production declined sharply, as did profits and employment. Unemployment jumped from 14.3% in 1937 to 19.0% in 1938. A contributing factor to the Recession of 1937 was a tightening of monetary policy by the Federal Reserve. The Federal Reserve doubled reserve requirements between August 1936 and May 1937 leading to a contraction in the money supply.
The Roosevelt Administration reacted by launching a rhetorical campaign against monopoly power, which was cast as the cause of the depression, and appointing Thurman Arnold to break up large trusts; Arnold was not effective, and the campaign ended once World War II began and corporate energies had to be directed to winning the war. By 1939, the effects of the 1937 recession had disappeared. Employment in the private sector recovered to the level of the 1936 and continued to increase until the war came and manufacturing employment leaped from 11 million in 1940 to 18 million in 1943.
Another response to the 1937 deepening of the Great Depression had more tangible results. Ignoring the pleas of the Treasury Department, Roosevelt embarked on an antidote to the depression, reluctantly abandoning his efforts to balance the budget and launching a $5 billion spending program in the spring of 1938 in an effort to increase mass purchasing power.
Business-oriented observers explained the recession and recovery in very different terms from the Keynesian economists. They argued the New Deal had been very hostile to business expansion in 1935-37. They said it had encouraged massive strikes which had a negative impact on major industries and had threatened anti-trust attacks on big corporations. But all those threats diminished sharply after 1938. For example, the antitrust efforts fizzled out without major cases. The CIO and AFL unions started battling each other more than corporations, and tax policy became more favorable to long-term growth.
On the other hand, according to economist Robert Higgs, when looking only at the supply of consumer goods, significant GDP growth only resumed in 1946. (Higgs does not estimate the value to consumers of collective goods like victory in war) To Keynesians, the war economy showed just how large the fiscal stimulus required to end the downturn of the Depression was, and it led, at the time, to fears that as soon as America demobilized, it would return to Depression conditions and industrial output would fall to its pre-war levels. The incorrect prediction by Alvin Hansen and other Keynesians that a new depression would start after the war failed to take account of pent-up consumer demand as a result of the Depression and World War.
The government began heavy military spending in 1940, and started drafting millions of young men that year. By 1945, 17 million had entered service to their country, but that was not enough to absorb all the unemployed. During the war, the government subsidized wages through cost-plus contracts. Government contractors were paid in full for their costs, plus a certain percentage profit margin. That meant the more wages a person was paid the higher the company profits since the government would cover them plus a percentage.
Using these cost-plus contracts in 1941-1943, factories hired hundreds of thousands of unskilled workers and trained them, at government expense. The military's own training programs concentrated on teaching technical skills involving machinery, engines, electronics and radio, preparing soldiers and sailors for the post-war economy.
Structural walls were lowered dramatically during the war, especially informal policies against hiring women, minorities, and workers over 45 or under 18. (See FEPC) Strikes (except in coal mining) were sharply reduced as unions pushed their members to work harder. Tens of thousands of new factories and shipyards were built, with new bus services and nursery care for children making them more accessible. Wages soared for workers, making it quite expensive to sit at home. Employers retooled so that unskilled new workers could handle jobs that previously required skills that were now in short supply. The combination of all these factors drove unemployment below 2% in 1943.
Roosevelt's declining popularity in 1938 was evident throughout the US in the business community, the press, and the Senate and House. Many were labeling the recession the "Roosevelt Recession". In late December 1938, Roosevelt looked to gain popularity with the American people, and try to regain the nation's confidence in the economy. His decision that December to name Harry Hopkins as Secretary of Commerce was an attempt to achieve the confidence he so badly needed. The appointment came as a surprise to most because of Hopkins' lack of business experience, but proved to be vastly important in shaping the years following the recession.
Hopkins made it his mission to strengthen ties between the Roosevelt administration and the business community. While Roosevelt believed in complete reform (The New Deal), Hopkins took a more administrative position;[clarification needed] he felt that recovery was imperative and that The New Deal would continue to hinder recovery. With support from Secretary of Agriculture Henry Wallace and Treasury Secretary Henry Morgenthau, Jr, popular support for recovery, rather than reform, swept the nation. By the end of 1938 reform had been struck down, as no new reform laws were passed.
The economy in America was now beginning to show signs of recovery and the unemployment rate was lowering following the abysmal year of 1938. The biggest shift towards recovery, however, came with the decision of Germany to invade France at the beginning of WWII. After France had been defeated, the U.S. economy would skyrocket in the months following. France's defeat meant that Britain and other allies would look to the U.S. for large supplies of materials for the war.
The need for these war materials created a huge spurt in production, thus leading to promising amount of employment in America. Moreover, Britain chose to pay for their materials in gold. This stimulated the gold inflow and raised the monetary base, which in turn, stimulated the American economy to its highest point since the summer of 1929 when the depression began.
By the end of 1941, before American entry into the war, defense spending and military mobilization had started one of the greatest booms in American history thus ending the last traces of unemployment.
