The hundreds of existing sales taxes in America use honestly stated "exclusive" rates. Apples to apples.
Fair Taxers and honesty don't mix.
The more I read about the “fair tax”, the more I’m starting to see that. When I have questioned it, I got insults back. They seem to be so obsessed with the concept they don’t want to even try to understand the person questioning it. I usually have found that the worse ideas in life are pushed by arrogance.
