Some data on the tax rates paid by different income groups show that the Bush tax cuts had more impact at the bottom. The top 5% of taxpayers are payin the same rate now that that group paid in 1990. On the other hand the rate paid by the bottom 50% is about half what it was in 1990. The Clinton tax increase had pushed up the rate for the top 5% from 23 to 28%, while the bottom 50% rate was about the same as in 1990.
