It won't change to a sales tax but I would like it. To me it would be very fair. You'd be taxed on what you consume.
Opinion: Federal Sales Tax
I'm with Amazing on this one. This country did quite nicely without an income tax for over a hundred years. Interesting little bit of history. The original wording of the amendment limited the tax to 3%. That was taken out because people were afraid that Congress would interpret that to mean that they could actually take that much of somebody's money.
Not to be confused with The Rabbit.
Another benefit of a Federal Sales Tax is that the Legal Aliens would have to pay it. My understanding is that they are in this country now working, but don't have to pay taxes. If we had the sales tax, maybe they wouldn't be exempt at the register too.
