If you are Alan Greenspan, you retreat from your 2008 epiphany in which you acknowledged your “state of shocked disbelief” that “the whole intellectual edifice” of your deregulatory ideology had collapsed. Now, you condemn reform efforts as “the current ‘anything goes’ regulatory ethos” — a phrase that paradoxically recalls your own failed policies at the Federal Reserve. In short, after driving the economy over the cliff, you offer to give driving lessons.If you are JP Morgan’s chief investment officer, you refute the statement that your chairman and chief executive, Jamie Dimon, made to the FCIC in 2010 blaming the failures of major financial institutions on “the management teams 100 percent and . . . no one else.” You revise your opinion on the causes of the crisis to instead focus blame on government housing policies. The source for this newfound wisdom: shopworn data, produced by a consultant to the corporate-funded American Enterprise Institute, which was analyzed and debunked by the FCIC report.
