Since 1978, the U.S. has cut the highest marginal earned-income tax rate to 35% from 50%, the highest capital gains tax rate to 15% from about 50%, and the highest dividend tax rate to 15% from 70%. President Clinton cut the highest marginal tax rate on long-term capital gains from the sale of owner-occupied homes to 0% for almost all home owners. We've also cut just about every other income tax rate as well.
During this era of ubiquitous tax cuts, income tax receipts from the top 1% of income earners rose to 3.3% of GDP in 2007 (the latest year for which we have data) from 1.5% of GDP in 1978. Income tax receipts from the bottom 95% of income earners fell to 3.2% of GDP from 5.4% of GDP over the same time period.
