I nowhere said that "exemptions would be changed". My comment on that had quite adifferent meaning in that changing them was actually quite difficult - which I believe is the way it should be.
I agree - and that's the American way. But the word "legally" is both important and observed by most people (there will always be some who do not do that, though). With the FairTax, legally not paying taxes on items purchased at retail is not so easy to do. Stop and thing, something like 80% of the retail trade (dollarwise) in this country is done by about 20% of the sellers. Wal-Mart is quite unlikely to rish its business to give either you or me a 23% knockoff of the legally-required tax.
There's also no shame in legally paying taxes (in contrast to some presently in the illegal economy who evade it - illegally, of course).
