"* This results in middle and lower classes bearing more of the tax burden"
no, that's what's happening now. the working class pays income tax, and embedded taxes on goods, the rich have special interest deductions, and workarounds lightening thier tax load.
and are you working under the assumption that the rich will suddenly stop living like they're rich? your averge person will spend more money if they have more money.
you're missing it because you're looking in the other direction. you're trying to calculate income tax percentage from a consumption tax.
take a step back and instead of figuring how much of the income is spent on taxes, figure out how much is spent.
the rich a a whole will no doubt be spending more on luxuries, and thus still paying more taxes. the fairtax hits you harder the more you spend, not harder the more you earn.
