From an interview with economist Milton Friedman by television talk-show host Phil Donahue in 1979:

Phil Donahue: When you see around the globe the maldistribution of wealth, the desperate plight of millions of people in underdeveloped countries, when you see so few haves and so many have-nots, when you see the greed and the concentration of power, did you ever have a moment of doubt about capitalism and whether greed’s a good idea to run on?

Milton Friedman: Well, first of all, tell me, is there some society you know that doesn’t run on greed? You think Russia doesn’t run on greed? You think China doesn’t run on greed? What is greed? Of course none of us are greedy. It’s only the other fellow who’s greedy. The world runs on individuals pursuing their separate interests. The great achievements of civilization have not come from government bureaus. Einstein didn’t construct his theory under order from a bureaucrat. Henry Ford didn’t revolutionize the automobile industry that way. In the only cases in which the masses have escaped from the kind of grinding poverty you’re talking about, the only cases in recorded history are where they have had capitalism and largely free trade. If you want to know where the masses are worst off, it’s exactly in the kinds of societies that depart from that. So that the record of history is absolutely crystal clear that there is no alternative way, so far discovered, of improving the lot of the ordinary people that can hold a candle to the productive activities that are unleashed by a free enterprise system.

Donahue: But it seems to reward not virtue as much as ability to manipulate the system.
