Well actually there have been two longtime loyal FairTax supporters who have admitted it is a lie, so really it is just you and geezer who continue this, either out of stupidity or flat out dishonesty.
That assumption is neither a lie nor even a valid indication of what will happen in the real world. In fact, wages are highly unlikely to go down at all as has been pointed out to you many times. Even the 75 recognized economists say in their endorsement letter that said the FairTax would:
"Enable workers and retirees to receive 100% of their paychecks and pension benefits, ..."
As for the "... stupidity or flat out dishonesty ..." you accuse others of, you might look to your own statements as they are replete with some outstanding examples thereof.
In addition, the reporter in the lead-in article DID, contrary to your claim, quote the left-wing long-time ardent FairTax opponent William Gale with his anti FairTax venom. Also Slemrod (hardly pro-FairTax) and the "tax law professor" who is obviously going to be pro Status Quo since his livelihood depends upon it.
The article is exceedingly biased and for you to not recognize and admit that you'd have to be blatantly foolish or downright ignorant.
