Is "greed good" as declared by Gordon Gekko? Sam Polk's article in yesterday's New York Times suggests otherwise. In fact, he gives a candid account of the problem he had, attributing his own drive for money to "wealth addiction." Although he amassed a sizable fortune as a Wall Street trader a few years ago, he never felt he had enough. Personal introspection, with assistance from psychotherapy, led him to understand that his greed, and that of others in the industry, is essentially the same as that with drugs or alcohol. Polk has since left Wall Street for social activism, starting Groceryships, an organization working to promote nutrition education among poor families.
