Paul Krugman won the Nobel Prize for economics. Professor Krugman is a personal hero of mine, for his ability to explain income inequality, the housing crisis, and the relationship between greed and our troubled economy. In addition to his scholarly work, he writes a column in the New York Times. He understands the real problems faced by the middle class. You can read his blog here. Congratulations Dr. Krugman -- keep up the good work!
