I'm not sure if Cain's plan

I'm not sure if Cain's plan has it, but previous proposals of federal sales taxes had caveats for if you earn less than X amount of money or for your first X amount purchased there was no tax charged. And this necessitated having a system of knowing who got the tax and who didn't, thus even for cash purchases an ID would need to be presented. If this is part of the plan it's very dangerous, because the federal government can have complete accounting of what each person is buying and where. No privacy. And it's really easy to fabricate evidence against someone. It also would make it really easy to "turn off" someone's ability to purchase goods if they were to be put on a no-fly style list, for example.
