It's not insanity but Bernanke and Obama have essentially killed capitalism in order to preserve a bubble economy that they had to save. The housing bubble basically launched huge gains in income to middle tier workers (plumbers, welders, eletricians, real estate agents, builders, etc, etc) allowing these people to spend more money driving up prices in property and demand for cars, vacation homes, etc. Also remember that this increase in property prices also increased taxes in all states through property taxes which meant increases in pay for all municipal workers. This virtuous cycle of spending was great until we found out that it was all a scam based on loose credit and home sales to unqualified buyers (even a dog bought a house).
So if they didn't pump a trillion dollars a year in into the economy what you would of seen was a massive deflationary spiral globally which would of meant a huge recession that would of meant 30% unemployment for years and years. So the US is bankrupt which is why they have to have the raise the debt limit debate every year because the US is paying one credit card with the other credit card hoping that no one notices. It definitely saved the economy but the next bubble is already forming into the stock market bubble as the stimulus money is creeping into sales and the stock market essentially forming a false economy on its own.
