Without banking regulation, the SEC, the TVA and other reforms the country probaly couldn't have gotten out of the Depression. But most people know the New Deal only helped us survive the depression, not to end it. The New Deal just wasn't big enough to jump statrt the economy, that took WW2 to do.
Absolutely false. It's what caused the Depression to be more than just a Recession. Hoover started it with his policies, and FDR finished it. WW2 wasn't even the catalyst as many see it to be. Spending by the government does not create prosperity, period; rather it results into despair, as seen 1930-1945.
In fact, using your logic, we should've seen the greatest depression in the history of mankind in 1946 when the war ended and when government spending shrunk dramatically. That absolutely wasn't the case. Prosperity ensued in 1946.
