Columnist Floyd Norris reminisces about when people used to fawn over Alan Greenspan, former chairman of the Federal Reserve, which appeared to be above criticism. Times have changed as current Fed Chairman Ben Bernanke has criticism flying at him from all directions. Americans are attacking Bernanke for printing money, and world leaders say he is undermining the dollar to help U.S. trade. Some Republicans have floated the idea that getting rid of the Fed would be a wise move. Neither the criticism nor the previous praise of the Fed is altogether justified, Norris writes.
