I assume you must have plenty of guarantees in hand for your returns under the present system. Right? Yes, I'm an optimist. But at least the Fair Tax Act (HR 25) gives us plenty of room for optimism. And the economists whose analyses support it are entitled to some weight of consideration.
And I never mentioned "returns", that changes the subject. I'm not interested in changing the subject, which is, your statement that prices would go down. A preposterous thing when not identified as a projection. Crystal balls will be in short supply if this thing picks up steam. (An unlikely prospect)
