it includes other provisions and it may be that workers are less productive because they feel ailnated. there is an issue in terms of what is the cost of higher growth. people often cite president clinton when he took office. president bush cut taxes and the economy didn't do very well. ronald reagan was convinced to race taxes and he was concerned that the deficits would entail huge economic costs. if we can't figure out a way to raise enough revenue. deficits are going to entail more costs by raising interest rates and making it harder for people to buy homes. finally, the issue isn't whether we should necessarily raise tax rates on higher income people and the best way to do that, i think most economists would agree to broaden the tax base and eliminate most of the preference items which are skewed towards people with higher incomes to eliminate as many preferences as possible so it is possible to lower tax rates as the same time as you make them more progressive. the b bibartisan program propos the same thing. and with that, i think i will pass it off to bob. >> thank you. bob? >>
