In your two posts to mine you have completely missed the point in your zeal to defend capitalism. The professor did not compare the two and I didn't say he did.
His premise is that a successful capitalist society, combined with the natural human desire to help, will eventually lead to socialism.
When I talked about how either capitalism or socialism both ignore human nature it was NOT a comparison. It's simply a statement of the truth. In a purely capitalistic society greed, avarice and the constant grab for power will ignore humanity just as a purely socialist society will humanity by stifling innovation, artistic expression and the human desire to do better.
A system which has a free market economy is not necessarily driven by avarice, greed, and the grab for power.
It simply means that people are free to trade their services without undue government regulation.
It isn't a system of commerce that makes people greedy and it isn't government regulation that removes it.
You are somehow suggesting that human greed can eliminated by socialism...and that's just not true.
And what is a capitalistic society anyway? Are you against freedom?
I think you are confused as to what capitalism is.
