Has Ben Bernanke learned his lesson?

I'd thought that if there were any lesson that Federal Reserve policy makers had learned from the stagflation the Fed caused during the 1970s (weak growth in GDP coupled with high unemployment and high inflation) it's that the Fed can'...t fool people into creating real economic growth over the long term by creating an excessive growth rate in the money supply. As the monetary bubbles caused by Greenspan and Bernnanke this decade show, however, neither one seems to have learned the lesson. I'm not as optimistic as the Wall Street Journal editors that somehow Bernanke has learned his lesson between 2007 and now.
