Liberals have been indoctrinted to believe that FDR's spending helped America during the depression.
Let's not make the same mistake, tell team Obama to not follow Hoover's and FDR's failed strategy because the facts surrounding FDR and the Great Depression tell us something else. "Fully 17.2 percent of Americans, or 9,480,000, remained unemployed in 1939, up from 16.3 percent, or 8,020,000 in 1931". 
So rather than just showing FDR's failures based on statistics, let me use FDR's Secretary of The Treasury own words.
"Here was Morgenthau, the secretary of the treasury, an expert on finance, a fount of statistics on the American economy during the 1930s; his best friend was the president of the United States and the author of the New Deal; key public policy decisions had to go through Morgenthau to get a hearing. And yet, with all this power, Morgenthau felt helpless. After almost two full terms of Roosevelt and the New Deal, here are Morgenthau's startling words -- his confession -- spoken candidly before his fellow Democrats on the House Ways and Means Committee":
We have tried spending money. We are spending more than we have ever spent before and it does not work. And I have just one interest, and if I am wrong...somebody else can have my job. I want to see this country prosperous. I want to see people get a job. I want to see people get enough to eat. We have never made good on our promises....I say after eight years of this Administration we have just as much unemployment as when we started....And an enormous debt to boot!
