It's not just a function of progressive income tax brackets, either. They'd be paying more than their "fair share" even with a flat income tax rate.
The state legislature in New Jersey had to pass a mid-year budget adjustment a couple of years ago after ONE TAXPAYER moved out of the state. He was a Wall Street hedge fund guy, and it was estimated that he paid something like $100 million to $120 million in state income taxes for the last year he lived in New Jersey. There's no way in hell a single taxpayer uses $100M+ in taxpayer-funded services no matter how you look at it. So, yeah -- he was paying far more than his "fair share."
