When two people order a steak, regardless of their income, they get the same thing. On the other hand, one of the largest services a government offers its citizens is protection of the citizens' persons and wealth, both from domestic and foreign threats. The value of that protection is relative to how much each citizen is worth. If you're in debt, like many Americans, you're basically getting protection only for your person, as you have little to no wealth to protect. On the other hand, if you're worth billions, the government is protecting your wealth as well. It only makes sense that the more you have to protect, the more you should have to pay.
