TAX WHAT YOU DON'T WANT, NOT WHAT YOU DO:

If VAT, Ditch the Income Tax (George Will, 4/18/10, Real Clear Politics)

Although the nation's welfare often varies inversely with that of the political class, a VAT would ameliorate a real problem: Americans consume too much and save too little. Furthermore, today's baroque tax code drives economic distortions and enables corruptions.

Corporations do not pay taxes, they collect them, passing the burden to consumers as a cost of production. And corporate taxation is a feast of rent-seeking -- a cornucopia of credits, exemptions and other subsidies conferred by the political class on favored, and grateful, corporations. Because the income tax is not broadly based, it radiates moral hazard: Its incentives are for perverse behavior. The top 1 percent of earners provide 40 percent of that tax's receipts; the top 5 percent provide 61 percent; the bottom 50 percent provide 3 percent. So the tax makes a substantial majority complacent about government's growth.
