but will also eliminate all federal taxes.It does not "eliminate all federal taxes". It's a federal tax that replaces a few and taxes the rest.
Well, OK, let's be more specific even though the people would have the information if they visited the FairTax website.
The FairTax eliminates income taxes, payroll taxes, estate taxes and gift taxes in addition to eliminating the IRS and calling for the repeal of the 16th amendment and the destruction of the income tax records.
Saying it replaces "a few" taxes as you do is merely a Status Quo Lover's attempt at misdirection hoping the word won't get out ... but it is getting oput despite your efforts, Looey.
"It's a federal tax that replaces a few...."
The FairTax replaces all current federal taxes except for excises, which comprise about 5% of total federal revenues. If you are an SQL, 95% is the equivalent of "a few".
