A better model of the human condition:
The case for free enterprise, for competition, is that it's the only system that will keep the capitalists from having too much power. There's the old saying, "If you want to catch a thief, set a thief to catch him." The virtue of free enterprise capitalism is that it sets one businessman against another and it's a most effective device for control.
Anybody who buys the con that "government" == "virtue" is a fool.
