Reply #4: Good question.

I'm really glad you asked this because it touches on one of the biggest arguments against socialism. The human nature argument. First of all, I'd argue that capitalism doesn't offer unlimited opportunity, because if you look at our society there are people with college degrees who are waiting tables at restaurants. There were PhD in Egypt waiting tables and other service level jobs and Egypt wasn't socialist.
Second of all, to address the human nature argument. What is human nature? The Marxist/Socialist response would be that human nature is a product of our environment and society, under capitalism the goal is to gain as much wealth as possible so, of course, greed is the norm. People have been raised to think that way their whole lives, they don't know anything else. In a socialist society the greatest goal would be service to society, you would still be rewarded for your contributions to society but not only would you gain some material compensation you would gain the respect of your fellow man, which in my mind is far better a reward than a BMW. Does that address your question?
