the 3.75% applies only to the illegal income when spent under the current system.OH so currently the seller would have $21.25 after taxes to spend but with your plan he would only have $2.00 after taxes to spend...So how is that different from the legal way again Einstein?
You don't seem to have a problem with your math showing what's illegal but you can't seem to make your math work your way for what is legal.
If the seller had the same margin with both the IT and the FairTax, Looey, he'd actually have MORE to spend under the FairTax since his profit would not be taxed - which it is under the IT. The seller would have the entire margin of his profit - untaxed.
It is the buyer (and not the seller) who is paying the FairTax remember? The seller merely collects and forwards it (and is paid for doing so).
Oh, and it's not mathematics ... it's arithmetic.
