When you think of it, in today's economy, the role of the wizard is being played by the Federal Reserve Bank. Facing a difficult economic situation, made worse by the inaction of a bickering Congress and essentially paralyzed government agencies, the Fed has found itself forced to take on the role of savior. And since its massive emergency interventions in 2008, it has felt a moral obligation to stay engaged, a role which, over time, it seems to have pursued more willingly.
In trying to do good, the Fed has confronted more than the considerable dark forces of disorderly economic and financial deleveraging. It has also had to overcome the (not-so-occasional) headwinds from a disruptive Congress and a Europe unable to decisively overcome a regional debt crisis.
