Yes, the Second World War got the USA out of the depression. Massive employment, massive mobilization, massive job creation...no bombing or invasion of mainland America to mess things up, relatively small losses in American lives (compared to most combatant nations), massive war production. All you need to get out of a depression is a really large and definitely winnable war fought entirely on other people's land and paid for by other people's gold and other people's devastation! (meaning that of the UK and Europe)

That window of opportunity doesn't exist now. Such a profitable BIG war is no longer feasible for America...or anyone else, mostly due to the nature of today's strategic weaponry.
