There's no end to the crazy tax ideas I come up with. What do you think about this one? It requires a computer. Everybody has a tax rate, the rich have a high rate and the poor have a low rate, but the only tax is paid as a consumption tax at the retail level. You'd have to swipe your tax card for every purchase. There would be a great incentive for the black market but I'm not too worried about that. Not really advocating this, just interested in where I have gone wrong.
