One other crucial difference is that the U.S. today is far less likely to engage in the stupid measures that FDR implemented in the 1930s to "fix" the Great Depression -- which ended up making the Depression far worse than it would have otherwise been.
You might consider that Bush has adopted the FDR receipe of priming the economy with deficit government dollars. FDR filled the job needs that private industry did not provide. FDR was doing OK until the Commies took him over.
Some history. "The Great Depression brought about severe economic hardships in America and around the world. People were opportunistic, wanting any type of advantage that could be given to them. One such group of people were the World War I veterans and their families; who wanted a bonus for their services in the Great War now, instead of in 1945. During this turbulent time, the United States government was very concerned with political uprisings that tried to overthrow the government. The government's great concern about riots and political uprisings during the Great Depression led to hasty actions to quell the Bonus March demonstrations, created animosity towards President Hoover, and eventually forced him out of office."
Actually it was a war that ended the Great Depression.
