Here is the thing I never understand: where is all this libertarianism before people get rich on the back of our society? Bill Gates started a business in the U.S. with full notice of how our system works. It's not like we decided after the fact "hey, this guy is rich, let's take his money." Indeed, he's gotten an even better deal than he originally bargained for--taxes now are lower than they were in the 1970's and 1980's.
