What's the matter with people being rich, anyway? they still spend their money. Someone had to build their mansions (and Porsches) and paint their portraits... since all the money rich people have ends up in the hands of not-so-rich people sooner or later, what is the difference between taxing the rich and taxing the poor?
Most of you seem to subscribe to a very Marxist perspective. What makes you think the government can do better with tax dollars than privately owned, competitive companies can do with their own money?
