There's a a real word for this. 'Plutocrat.' A member of the 'plutocracy': a government controlled by the wealthy.

If we had a flat tax (say, 20% on both capital gains -- short and long term -- and income tax), we wouldn't have any of this nonsense. But then, we'd have a lot of out-of-work lobbyists (read: politicians in 'retirement') and people who work for non-profits and charities...

i would argue plutocrat doesn't have a ring to it, and makes the user sound like onna them lib'ral elitists
