also, its really not that big of a deal
Power. Everyone loves power. I'm guessing that the rich like it more than most people, on average. Another bad idea is to give the rich two votes apiece in any election. That's double the power of other citizens. But don't worry that it will distort election results. There aren't that many rich people, and they are somewhat divided in their opinions, just like the rest of the world. And realistically, is the candidate who gets 51% of the vote always better than the one who gets only 49%? That's a risk I'll take.
