The FLSA outlawed child labor, established a federal minimum wage, and required overtime pay for certain employees who work in excess of forty-hours per week.[203] He also won passage of the Reorganization Act of 1939 and subsequently created the Executive Office of the President, making it "the nerve center of the federal administrative system."[204] When the economy began to deteriorate again in mid-1937, during the onset of the recession of 1937–1938, Roosevelt launched a rhetorical campaign against big business and monopoly power in the United States, alleging that the recession was the result of a capital strike and even ordering the Federal Bureau of Investigation to look for a criminal conspiracy (of which they found none). He then asked Congress for $5 billion (equivalent to $94.25 billion in 2021) in relief and public works funding. This managed to eventually create as many as 3.3 million WPA jobs by 1938. Projects accomplished under the WPA ranged from new federal courthouses and post offices to facilities and infrastructure for national parks, bridges, and other infrastructure across the country, and architectural surveys and archaeological excavations—investments to construct facilities and preserve important resources.
