And what you forget to mention, as anyone who pines for the good old days of a 90% bracket does, is that everyone was paying significantly higher taxes then not just the so called rich.
in 1954 when the top bracket was 91% the lowest was 20% and someone earning 40K was in the 56% bracket.
So be careful what you wish for, you just might get it.
yet $40k in 1954 is equal to $343k today. and the 56% tax bracket is not for all income, it is a graduate system. this it the current graduated tax rate system:
10% on taxable income from $0 to $8,700, plus
15% on taxable income over $8,700 to $35,350, plus
25% on taxable income over $35,350 to $85,650, plus
28% on taxable income over $85,650 to $178,650, plus
33% on taxable income over $178,650 to $388,350, plus
so if the top rate was 56% today, it would only apply to income over $178,650. they would still pay the lower rates on all income below that according to the tax tables.
