"The market system, as it gets more specialized, will give more and more to the top people. If we were back in 1800 and we were all working on farms, you'd probably be worth more a little more than I am, because you'd work harder and be stronger. But the top person working at a farm would be worth one-and-a-half to maybe two times what the bottom person was. But as we get more and more specialized, the guy that is the best at knocking out some other guy who weighs two hundred pounds is worth ... thirty million dollars a fight. Now, he's worth thirty million dollars a fight because someone invented television and cablevision. As we get more specialized, the rich will get even richer."
