I guess it's hard for those literate on the subject of the depression to realize anybody out there still fails to understand it was a direct product of Hoover and FDR's economic interventionism. Hoover's strong policy reaction to the crash and then the New Deal caused the Depression. It ended after the war because the government was forced to roll back much of the New Deal in order to win the war.

Countries that did not much intervene after the initial financial crash recovered in the space of a few years. The decade long depression was more of an American phenomenon caused by FDR.
