You don't seem to have read the FairTax bill. Please look at it on the THOMAS website and see that it is NOT an additional tax but abolishes the income tax and the IRS and calls for repeal of the 15th amendment.
Hybrid taxes (VAT and income, sales and income, etc.) are monstrous and you'll find that most FairTax supporters both realize this and are adamently opposed to any hybrid tax system. That's why it is necessary for all of us to hammer on our Congressmen to pass the FairTax bill pretty much its present form.
Good ... since you know how much you pay; based on your gross income what % do you now pay in federal taxes?
You needn't give dollar figures, just % of the gross income rounded, say, to the nearest integer percentage point.
"We will always have the IRS and the income tax...."
I discussed the importance of abolishing the income tax because of its tendency to form a habit of servility in the souls of a people that accept it. Servility of soul is bad not only in itself, it is also an open door through which will soon walk the abuses of ambitious government power. Leaders who find themselves with governmental power over a servile people will be quick to conclude that such a people exist to serve them.
