What did they do? I'm getting what you mean.Okay here is My suggestion.
Top US Marginal Income Tax Rates, 1913--2003 (TruthAndPolitics.org)
Study that chart... and see what each tax cut, did to the top bracket, and what each increase did the to the top bracket.
That would certainly be a start but I do not think the GOP would ever go along with this.Now lets compromise.... lets not increase the tax percentage at all, and I believe this could get enough support to pass both houses, lets just drop that “taxable income over” figure back to $200,000 that Obama wants to use. Obama likes to use 5% of the population making more then that … I disagree with that number so will cut it in half. That effects only 2.5% of our working people. And they would be paying $60,760.(2/3s of that 91,000 you constantly harp about) more each .. that equals roughly 225 billion dollars in added revenue.
Now for this tax increase, of 225 billion, I want not 6 billion that dem's want, not 60 billion that rep's want but 112.5 billion dollars in cuts on this years budget.
