The tax base for a NRST is the tax on sales or on the products thereof, not individuals, so it is important if we are to discuss a subject to get the definitions correct, or, as it is done in a legal document, set the definitions beforehand, for if we wish to engage in constructive discourse we must have a mutual understanding of terms, even if that means you are incorrect. Or if you wish to write in a language other that English, be my guest.
