Rich people don't usually get handouts from the government, but they get something more valuable - a social order, enforced by the government, that allows them to be rich. Suppose you were rich, but you lived in a place where rich people tended to get kidnapped and held for ransom - being rich wouldn't be quite as good of a deal. The social order disproportionately benefits the rich, so they should pay more to keep it going.
