Since you feel very strongly about this, explain exactly why VAT is bad for us...
Sorry to interject, but I can't help myself.
The answer to your question is simple:
VATs are HIDDEN.
Hidden taxes are prone to political manipulations and hiding the true cost of goernment from the citizenry.
If Hastert wants to promote a VAT, I will oppose him. If he wants the FairTax, he will have my undying and active support.
