From Timothy Egan at Opinionator at The New York Times:
By almost any measure — social, political, economic, logical — Herman Cain’s 9-9-9 tax plan is nuts, nuts, nuts. Go ahead and jack up the price of nearly everything that moves in the United States with a 9 percent national sales tax on all new purchases and services. Talk about instant branding: every time you buy something, you’ll be hit with the Herm Cain tax at the checkout line.
And this is just the start. The nearly 50 million filers whose main federal tax is now a payroll deduction and not an income tax would see their overall bill from the government increase by nearly 100 percent. This conclusion comes from the economists and fact-checkers who have actually looked at the napkin sketch of a plan Cain got from some accountant friend of his in Cleveland.
