The whole fair tax thing to me seems like just a bunch of talking points:

Keep your whole paycheck

No income tax

No capital gains, corporate, or death tax

etc etc just keep regurgitating it.

The thing I don't like about it is that the entire tax burden is placed on consumption. And consumption is a really small piece of the pie compared to capital gains etc. I'd read the books but honestly I have more important stuff to read for school/career that takes priority. I've read enough both for and against to know what it is and why I don't support it.
