For the naysayers,

Is money really the root of all evil? Is the pursuit of profit evil? Today's anti-Capitalists would have you believe the answer to both questions is "yes", but take a closer look. Did Henry Ford labor hard to create a automobile because he wanted to serve humanity? Of course not; he was pursuing profit. When you go to a nice restraunt where service is excellent, do you really think those restraunt workers go to work each day just to serve humanity? No, they go to work to satisfy their need for income. When we each pursue profit and income to satisfy our own immediate needs....the whole economy benefits. Adam Smith called this the invisible hand effect; everything falls into its most needed place when people have economic freedom. So you can see that Karl Marx was nowhere close on his judgment of Capitalism.
