Absent from this article is the fact that the Fed did not have rounds and rounds and trillions of dollars of stimulus in the past, or anything comparable in scale. Up till now, people are still trying to justify the disappointing growth. It has been 7 years into this emergency mode now. And the market has gotten very used to it - always not a good thing in financial markets. What happens when the next problem hits? How do you get into an emergenci-er mode than this current 7-year emergency mode? It would be really interesting to see what happens to the market in the next 1-3 years.
