Taxing the Rich Does Not Work

Arthur Laffer, at the  WSJ:

If only more of today’s leaders thought like JFK. Sadly, in the debate over whether to extend the 2001 and 2003 tax cuts, and if so whether the cuts should be extended to those people who are in the highest tax bracket, there is a false presumption that higher tax rates on the top 1% of income earners will raise tax revenues.

Anyone who is familiar with the historical data available from the IRS knows full well that raising income tax rates on the top 1% of income earners will most likely reduce the direct tax receipts from the now higher taxed income—even without considering the secondary tax revenue effects, all of which will be negative. And who on Earth wants higher tax rates on anyone if it means larger deficits?

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. (See the nearby chart).
