I have seen it explained like this. Anyone with a taxable income of $250,000, that's after all deductions so they may make $400,000 - $500,000 in gross income, would have a tax increase. For every $1,000 in taxable income over the $250,000, they would pay $30.00 more in taxes. The amount of taxes for the first $250,000 would remain the same as it is now. I don't see something like that hurting anyone. It would help the country.
