Does+Self-Interest+Serve+Others?

An article by Robert Frank in the NY Times suggest that Smith wasn't necessarily correct to argue that when individuals follow their own self interest that the community benefits. We have so many examples of how this assumption by Smith has been proven wrong. This article suggests that Smith's assumption is only true occasionally. But that very often self interest drives individuals to do things that help them while hurting others.... Ponzi investment schemes, pollution, etc.
