We have a bubble economy in America. Boom and bust. Been this way for nearly 150 years. It's not going to change because free enterprise allows two primal human emotions, greed and fear, to drive the economy. With every cycle though, the mood swings get wider. The good times get better, but when the bubble bursts we hit the ground harder. Of course, the folks who are now saying that all the QE the fed has done won't cause much inflation are the very same folks who said back in 2007 that housing prices could never fall enough to cause an economic crisis. Adding magic money to our system is like diluting a stock, and we are all familiar with the results of that.
