Of course, idiots like these dump monkeys don't realize that, even though the market crash of '29 was rather large, that the economic cycle would have straightened itself out. What Hoover tried, and the FDR compounded with federal spending "stimuli" up the yin yang essentially cemented the depression, then coupled with a socialist takeover which, thankfully, never fully materialized because the bulwark of the nation is, and always has been, conservative.
However, with the extended, government-caused depression, international business, which in the 20's had been greatly expanding, particuarly with continental Europe and Japan / Philipines, was suddenly curtailed. Because economic conditions were cut off, these countries accelerated their war mongering stances, which most probably was a good reason that WW2 started in the first place. Hitler used the bad economy as a springboard for spreading discontent and, subsquently, Arianism, justifying taking over Europe, while Japan felt they had carte blanche to rumble over Asia.
With a non-socialist foray in the 30's, we may not have prevented WW2 (other scenarios have Communism becoming much bigger), but maybe not. The point is that a wartime economy is not an economy that is normal, but is bent toward one thing: defense, not expansion of individual liberties. And that is key.
