Actually Roger, everyone contributed more then...everyone. It was not just the rich who received a tax cut. Everyone did. Now it is suggested to increase tax the rich only. Interestingly tax revenes INCREASED after the tax cuts and even over the Clinton years. Unfortunately due to both parties, spending also went up more and the price of oil increased.
As for the tax cuts, the intended effect was higher revenues which was achieved. Now go ahead increase taxes for the rich at this point in time and see what happens. You are not going to get investment form the middle class or poor people.
