Compared to what would have happened if everyone would have thrown up their hands and said, "Let the market sort itself out!", then yes everything is fine now. We have a fraction of the unemployment that we would otherwise have. And really, besides the current unemployment rate and the multi-term issue of national debt what do you have to complain about? Would you rather have 40% unemployment? Would you rather have the recession last 20 years instead of less than 2? Would you rather have lost the entire automobile industry? Would you rather have lost both the Afghanistan and Iraq wars due to lack of funding?
Is it impossible to prove an alternative that never came to pass? Yes. But the neat thing with money is that you can reverse it's flow if you want to turn back the clock to that alternative universe. So go ahead and see what happens. Or better yet, the next time we have a financial crisis just throw up your hands and say, "Let the market sort itself out!"
