Your position is correct, but nonetheless fails to account for human nature. It's all fine and dandy to have a system where, through 100% morally justified means, 1% holds all assets. Then you get an uprising of the other 99% and the whole country/system falls on its face. Morally, I don't agree with income redistribution for the sake of egalitarianism either; but pragmatically, one cannot but acknowledge its importance for the stability of a social system. And in the end, that trumps dogmatism.
