A "Supply-Side" Success Story

From Daniel J. Mitchell of The Heritage Foundation:

Why is the 2003 tax cut working so much better than the 2001 tax cut? Why is the economy performing better, for instance, and why are tax revenues growing faster than projected today compared to what happened after the 2001 tax legislation? The answer is that not all tax cuts are created equal. Tax cuts based on the Keynesian notion of putting money in people’s pockets in the form of rebates and credits do not work—and these are the tax cuts that dominated the tax legislation approved in May 2001. Supply-side tax cuts, by contrast, do improve economic performance because they reduce tax rates on work, saving, and investment. And since lower tax rates on productive behavior dominated the May 2003 legislation, it is hardly surprising that the economy has responded positively.
