I do think it would be worthwhile to shift to a pure
consumption-based tax system. I would do it by exempting all saving
from taxation. This could be done by consolidating all existing tax
deferred savings accounts--IRA's, Keoghs, 401k's, etc.--into one
savings vehicle. All contributions would be tax-deductible, all
withdrawals would be fully taxed at ordinary income tax rates.
Money inside the account compounds tax-free until withdrawn. There
would be no limit on contributions, no limit on withdrawals; no age
restrictions and so on. Since there are only two things that can be
done with income--either save or spend it--all taxation would
necessarily fall on consumption if such accounts
existed.
Expanding tax-free savings accounts (though not necessarily to the
maximal end that Bartlett suggests) happens to be a key tenet of
Rudy
Giuliani's tax plan. It seems to me that Giuliani might be able
to get some mileage by arguing that while the FairTax people have
their heart in the right place, he has a much more practical and
politically attainable way of shifting the tax burden toward
consumption. It would be, simultaneously, a sales pitch to people
intrigued by the FairTax idea and a subtle jab at candidates who
endorse the FairTax -- which includes Fred Thompson (or at least
it did at one point).
