I'm inclined to believe that government (US ) does have both a responsibility and a mandate (general welfare) to moderate economic crises with whatever resources available; the only question should be "what is the best method for doing so?"
Socialism you say? well yes perhaps so but that's far better than then another WWII germany/japan/china introduced by world-wide economic depression.
I view the stock market as the greatest form of legalized gambling. That's what it really is.
