Like the previous Quanitative Easings of the Fed, this one will just make an artifical short-term boost to the economy and result into another bust, giving the Fed an excuse to do more. Bernake said himself:
“We learned from the first three phases that we can’t run out. Trillions, Quadrillions, Whatever! We’ve got the Magic Porridge Pot. When we want more, we just keystroke it.”[/font]
He refused to put time limits on this new phase of QE: “No, it will never end. We’re going to buy everything. The whole damned planet. Some stars, too. I want to buy some Black Holes. Those things are dense; you can stuff a lot of money into them.”
