This video of Milton Friedman espousing greed and self-interest as expressed by free enterprise and free trade is making the rounds again:

Friedman reduces all of human behavior to greed. "You think Russia doesn't run on greed? You think China doesn't run on greed?" "You think the communist commissar rewards virtue?.... Do you think American Presidents reward virtue? Is it really true that political self interest is more noble than economic self-interest? Tell me where in the world you are going to find these angels who are going to organize society for us?"

Professor Friedman, we do not need nor do we seek angels to organize society. While Phil Donahue may have been flummoxed, none other than chief framer of the US Constitution James Madison had a complete answer to your prescription of increasing concentration of wealth and plutocracy, over 200 years ago.
