You discount the broadening of the tax base. The Fair Tax will not only capture the underground economy, tax cheats, and others when they spend their money but it also takes an equal amount from the average family. A family of four with one wage earner has one income taxed. (Two wage earners don't make any difference for this example.) However, that one wage earner buys for four, so his family now has effectively four tax payers.

High wage earners usually also buy more even if it is just for themselves. The rich certainly do. For one who has an interest in fairly viewing this that is not hard to see.

Correction: The Fair Tax will not only capture the underground economy, tax cheats....

When I do a service for $130, I can legally only keep $100 and must remit the $30 to the state. I have $100 to spend. When a drug dealer/prostitute get $130 they keep $130 and have $130 to spend. They cheated the fairtax system $30.

Come on, even the "Fair Tax" proponents gave up on that lie long ago.
