You too can do it yourself. All you need is a buy price, a tax cost component %, an other costs component %, and a sell price for each stage.

Do one with a tax cost component (Rob said 9%) and do one without it. The difference between the two is NOT 9%. That position is preposterous.

No he didn't.

"my statement was that if the most any input component of price was reduced was 9%..."

BTW, except for in failed Fairtax logic, only a sales tax or VAT could be an input component of price.

The difference between the two is NOT 9%.

Garbage in garbage out.
