A national sales tax will be as bad or worse, in terms of lost income, as the IRS - what we need is a flat tax of no more than 10%

The amount of government spending and how it collects the money that it spends are separate issues. I entirely agree that government needs to be smaller and less expensive, but as long as it exists it needs to be funded. The current income tax is about the worst system imaginable; it's complex, invasive, riddled with loopholes for special interests, it has huge compliance and enforcement costs, and it's biased against saving and investment. Regardless of how much of our money the government spends, the income tax needs to die.

Our income tax also discriminates against domestic production by not taxing foreign producers. If we keep the income tax, we ought at least to level the playing field by adding an equalizing tariff.
