BINGO! It ain't 'a wash'.
Under FairTax, those of us in the system will have more disposable income.
I think you finally see it, even though you stumbled upon it.
Even a blind hog will find an ear of corn every now and then.
The FairTax bill doesn't require the employer to pass on tax savings to employees. More disposable income doesn't automatically equal more purchasing power.
ONLY IF your employer gives it to you. You may continue to receive your current take-home pay while your employer uses that money to reduce the price of his goods.
The Fair Tax does NOT mandate that YOU get that money. Sure, you may. And if you do, prices (after the Fair Tax is added) will rise.
So yes, you have more disposable income. You'll need it to buy those more expensive goods.
