Jeorg, Let me chime in, here.
Now, I have a bit of savings. Yes, those earning were all taxed when I saved them, but they are in the bank now. They are earning a (very) little interest.
Now, they implement this fair tax. That money doesn't go away, it is still in the bank. Now, you can tell me that it was just de-valued by the amount of the tax, lets say 23%, but that doesn't happen right away. It only happens when I pull it out and spend it. Now, we never agreed on what that 23% meant. Did it replace the existing sales taxes? Or just add to them? If it added to them, then every think I now have to buy just got a third more expensive. Not a good thing.
But, if I don't spend that money, it is still there and making interest. If I wait, it doesn't loose any additional value. If I make additional money, then I save on those funds.
I would probably do just fine on the fair tax, but they will never do it... :(
