Wow. US Rep Steve Austria is now trying to blame the Great Depression on FDR, despite that fact that it began 4 years before he took office under the administration of GOPer Herbert Hoover. Hoover advocated a laissez-faire approach, and that resulted in the Depression deepening until FDR got into office. Nice work, Steve. Maybe you should stop reading the GOP talking points and crack open a history book.
If you do that, Steve, you'll discover that the Keynesian approach did work. The economy bottomed out in 1933 and began improving until 1937, when everyone thought that there was enough stimulus so the government pulled back spending, causing another recession.
