Flat Is the New Fair

Newt Gingrich and Jon Huntsman have tax rate reform proposals that move toward a flatter tax. But the candidate who comes closest to a true flat tax is Herman Cain, the former Godfather's Pizza CEO. His argument for a "9-9-9" plan puts the current income and payroll taxes in the shredder and replaces them with a 9% personal income tax with no deductions, a 9% net business income tax, and a 9% national sales tax.

That would be rocket fuel for the economy, though the combination of a federal sales tax and an income tax is a big worry. But at least Mr. Cain has super-sized solutions to an economy with super-sized problems.
