Capitalism is the best system because it’s based on human nature being intractable and universal; it assumes people will act according to their natures, and we are all driven by our nature to seek the advancement of our own self interest. Every Occupy protester goes to the protest out of his or her perceived self interest in getting something out of it. By the sound of their demands it appears that what they want and expect to gain is free stuff from the government.
Socialism fails and is the most unfair system because it depends on people acting against human nature and, that ain’t gonna happen. Adam Smith wrote in 1776, “It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest.” Nothing has changed, nor will it ever.
Take note Occupy protesters: If you think you need a government handout, if you think that is the answer to your problem, you will be poor all your life. And your precious government does-not-care.
