We could not ask for more,

A lot of the anti-Capitalists preach about the greedy rich and how they need to pay their fair share of taxes. But what if the rich already have given us more than we deserved? For example, the creator of heart medications has already given us a life saving drug; would it not be selfish to tell him "that's not enough, we want some of your money too."? Bill Gates helped us a lot by moving us out of the old 1980's computer systems and into more efficient systems. So maybe we ought to consider just how much the rich have already given us. By the way, shouldn't we owe them a thank you?
