Regressive tax policies? A gas tax is regressive, since both a rich guy and a poor guy with cars that get 20 mpg pay the same tax, and it's a larger percentage of the poor guy's income.
Lowering the tax for the rich so that it's not as high above that of the poor as it was before is not regressive, it's making it less progressive.
And that's not even all Bush did. I earn less than the max, so I get thousands in child tax credits taken off my taxes. People above that maximum income don't get that break.
A motorist who earns $250,000 per year, owns a vehicle with a fuel efficiency of 20 miles per gallon, and drives a total of 15,000 miles per year will pay the exact same dollar amount in fuel taxes as a motorist who earns $25,000 per year and drives the same vehicle over the same distance every year.
Yes, this is a "regressive" tax -- in that the fuel taxes paid by the second motorist comprise a much larger percentage of his income than the fuel taxes paid by the first one. But in this case, a regressive tax is the fairest means of taxation. The "rich" motorist doesn't use the road any more than the "poor" one, doesn't cause any more roadway deterioration or taffic congestion than the "poor" one, etc. So there is no sound reason why the "rich" one should pay any more in taxes than the "poor" one.
