For the dumbos: The "rich" pay the taxes that fund the current monstrosity that is the federal government.
Re the ?: Because the lag effect of income tax cuts, and the recovery of the world economy, generally takes 2 to 3 years to get rolling. The same can be said for the damage that Obama and the Dems are doing to this country. Things will get worse and we will be seeing a prolonged state of decline in this country because Dems love to Tax and Spend, and have never heard of cutting spending, even in the face of fiscal collapse. Costs for just health care and the Ponzi Scheme known as Social Security will blow deficits and the national debt out of the water (as will unfunded pension fund liabilities).
Damage due to the Demswill be with us for years to come and we will not bottom out for some time. Super-Tankers don't turn on a dime, and neither do economies. Expect a relatively dreary future young people. Good luck to generations X, Y, Z, and whoever else is left.
