Although I recently criticized James Pethokoukis (and others at AEI) for endorsing a welfare state, I recognize that Pethokoukis does some good policy work that’s usually supportive of freer markets. A good example is his article today in the Week, “Why Corporations Shouldn’t Pay Any Taxes—Zero, Zilch, Nada.” Quoting Boston University economist Laurence Kotlikoff, Pethokoukis writes, “Fully eliminating the corporate income tax . . . would cause ‘rapid and dramatic increases’ in U.S. investment, output, and real wages.” I’ve been making that case for years.
