I worry that a large sales tax and no income tax would severely hurt the economy. Doing so would encourage people to save their money, hurting the businesses, peole's salaries, and unemployment.

In the long run I'm betting only the rich would gain from this since they spend less as a percentage of their income than the poor. Also top management jobs are the last to go in a failing company. I'm pretty indifferent on the idea in general though...
