To directly answer your question, I am neither FOR the status quo nor AGAINST the FairTax.
I AM against irrational, impossible, and problematic promises. I AM against naive notions that once instituted that ANY new system is immune from tampering. I AM against the notion that any revenue neutral tax system somehow lessens everyone's tax burden. I AM against the notion that those who dare ask questions or point out inconsistencies have nefarious intent.
I AM for tax system reform (including wholesale replacement of today's system of income taxation) provided that such reform can live up to its claims. Time will tell if the FairTax is such a system; but as long as its proponents continue to sell it by making false claims, I'm not buying.
