Let's not forget state taxes. In some states it can be as high as 13% on top of the federal taxes.
As for gas tax, don't forget that revenues are going down because fuel economy is going up so Obama's administration has already proposed new ways to tax high mileage vehicles extra for using the roadways on top of the gas tax.
Just imagine the years it was 90% of the top tear....
Joe, while its true that the top bracket was much higher in the past there were lots of different ways to legally reduce your income taxes with what today are called 'loopholes' but back then were very acceptable.
The reality is that only a small portion of your income would have been taxed at very high rates because there were many ways to legally avoid high taxation through various deductions.
Further, high rates only applied to a VERY SMALL NUMBER of tax payers. Now the higher end of the tax rate spectrum applies to a much higher number of people.
