I too like the idea in principle but agree that the transition would be, shall we say, awkward. The feds taking your money will never be painless but it could be made less painful and more fair.
Part of the unfairness: People who get a lot of their incomes via cash, e.g. waiters, tend to pay less than their fair share. Also, some of the rich are able to underpay because they keep huge sums offshore and don't pay income taxes on this money.
Yes I agree we need a change.
I like the fair tax also.
However;
Without removal of the Income tax from the constitution we WILL end up with both. Not today, not tomorrow, but eventually.
The fair tax is a dead horse with out the removal of the constitutional incometax.
