A Lesson on the Laffer Curve for Barack Obama | Daniel J. Mitchell | Cato Institute: Commentary: 'The key takeaway is that the IRS collected fives times as much income tax from the rich when the tax rate was far lower. This isn't just an example of the Laffer Curve. It's the Laffer Curve on steroids and it's one of those rare examples of a tax cut paying for itself.

Folks on the right, however, should be careful about over-interpreting this data. There were lots of factors that presumably helped generate these results, including inflation, population growth, and some of Reagan's other policies. So we don't know whether the lower tax rates on the rich caused revenues to double, triple, or quadruple. Ask five economists and you'll get nine answers.

But we do know that the rich paid much more when the tax rate was much lower.'
