Welcome to the GOPs "Fair Tax/Flat Tax" Unless you want everything thing you buy to cost 10-20% more, just say no to these idiots. Sounded like a good idea, then we did the math and well.....

For someone who is supposed to be academic, you, sir, are a feaking moron. If you will examine the actual precepts of the Fair Tax, you will discover that the increase in "sales tax"is fully and completely rebated, to the extent that it is a
cost of living, in the form of a government check (or credit) to every taxpayer--the value of which is determined by the average expense of the number of people dependant upon the salary of the wage earner.
Secondarily, because all manufactures will no longer have to pay anything like a value-added tax, or sales tax on the items they purchase to manufacture their goods, their prices will be lower, and competition will then force them to reduce their prices by the 20% or so factor.
Your income will actually belong to you, without the 40% or so currently going to the government. If you spend you money on stuff, there will be a 20-something percent tax, however that 20-something percent will have been eliminated in the actual cost of the item bought. So in real dollars, it will be exactly the same price.
If you don't spend your money, like you might actually save a greater portion of the income earned by your personal sweat: it doesn't get taxed.
Quaker, I know you have been brainwashed by the liberal establishment, but try and kick the inclination to be stupid and give some actual thought to things before you spout your foolishness.
If you want to engage in a real discussion of the benefits of the Fair Tax, I'd love to school you.
