Honestly, while I might of given it some thought, the "FairTax(tm)" promoters are such a bunch of blockheads that just reading the material makes me want to take a aspirin. There is no correlation between their ramblings and the truth.
My rule of thumb is the longer it takes to explain something, the more likely its a lie.
Maybe you're not smart enough to understand? Why not indicate something specific?
