You fail to comprehend what Dr. Jorgenson's explaination means. It means you can't take your full salary and have prices fall significantly.
As I've told Rebbie and others - that's your interpretation ... your opinion. It is not necessarily the correct interpretation, but merely one of many.
It is - like the Dr. J. flap - a fairly meaningless difference of opinion. As the FairTax progresses toward a vote this will become more clear.
The salary is already being paid. It is not figured into the 23%. The 23% is from taxes paid by the employer. The wages affect the price, but they are a separate issue.
