There are two options when you're rich like Cuban is (clearly there's more but to dumb it down). You can acknowledge that while it took hard work, and luck to get where you are, you likely would not have done it if you hadn't been born into a society that fosters the ability to move up the social ranks. If Mark Cuban were born in Libya there's almost no chance he becomes a billionaire for instance. Or you can pretend like the reason you're rich is solely of your own doing, and that the world owes you something. Cuban seems to be the former, and while he's not going to volunteer to just give all his money away, he is trying to help society collectively improve. It's a stark contrast between his approach and say, the Koch brothers. I guess the best way I'd put it is Cuban is a capitalist who believes in the social contract.
