Watch this video of a GOP presidential debate on the FairTax proposal. Also check Wikipedia's page on FairTax.
Some very good points
were raised in that clip. Personally I would like to see us move to a flat tax
/ fair tax as I believe this would increase productivity. Tax on superannuation
savings should be removed or a tax break given. One point that was raised and I
believe that is why you would never see a Labour government introducing such a
system was the control governments have over with income tax etc.
