“The president intends to squeeze an extra $1.2 trillion over 10 years from a tiny sliver of taxpayers who already pay more than half of all individual taxes. It won’t work… Punitive tax rates on high-income individuals do not increase revenue.
The maximum tax rate fell to 28% in 1988-90 from 50% in 1986, yet individual income tax receipts rose to 8.3% of GDP in 1989 from 7.9% in 1986. The top tax rate rose to 31% in 1991 and revenue fell to 7.6% of GDP in 1992. The top tax rate was increased to 39.6% in 1993, along with numerous major revenue enhancers such as raising the taxable portion of Social Security to 85% of benefits from 50% for seniors who saved or kept working. Yet individual tax revenues were only 7.8% of GDP in 1993, 8.1% in 1994, and did not get back to the 1989 level until 1995.”
