Why would they want to pay more taxes? The joy of socialism is spending other people’s money. Neither the rich nor anybody else would waste their own money on crazy socialist programs.
What they want is to a) deflect envy, and b) keep their money. How they accomplish that is by pretending to be on the side of those that envy them. They do it because it works. Talk is cheap. Warren Buffet is the master at this. He talks about raising his taxes but does everything he can to avoid paying any. He claims to support the Democrats but donates next to nothing to elect them. And the Democrats think he’s a great. He’s completely off their attack radar.
