Anatomy of a Big Lie About Taxes

If you want to see Republican supply-siders squirm, ask them this simple question about the "Laffer curve": at what marginal tax rate does the “backward bend” (higher tax rates produce less revenue) begin? Even Laffer himself has not ventured an answer. Nor has anyone else.

Examine the depictions of the Laffer curve drawn by Laffer and you find the graph shows only two tax-rate numbers 0% and 100% at which the government collects no revenues — at 0% because their is no tax levied and 100% because there is no incentive to produce.
