To many observers, the Federal Reserve has never looked more heroic than it does right now. This past winter, America’s financial system faced the prospect of utter ruin. And, while the economy has suffered plenty in 2009, the worst did not come to pass. The banking system that lends to our employers, thereby allowing our economy to function, never did collapse. Now, many of the accolades for averting catastrophe are going to the Fed. President Obama himself ratified this analysis last week when he renominated Fed chairman Ben Bernanke for a second term.
