You need to do some more checking.
In preparing my response to your critique of the FairTax, I found this essay: https://en.wikipedia.org/wiki/Predicted_effects_of_the_FairTax.
It is, IMHO, a balanced discussion of the FairTax. (Pay no attention to the remarks attributed to Bill Gale (a Brooking Institute “scholar”). He is a through and through Marxist, and his absolute hatred for anything other than steeply progressive income taxes comes through.)
So, here is your homework assignment:
1. Read & digest the Wikipedia article; and
2. Read & digest the information you can find at the FairTax website: https://www.fairtax.org.
3. You might even want to read the legislation. It is short and easy to read and understand, unlike most of the stuff that gets written inside the evil beltway.
Now, please read and study this materiel with an open mind.
And, then, get back to me with your impression.
I’ll close with this: For me the FairTax is about FReedom!
Under FairTax, EVERY American will be FRee to work, earn, save and invest without the the heavy hand of government intrusion that the current income tax allows and encourages.
April 15th will become just another nice spring day!
FReedom is important, and FReeing the American people FRom the slavery of the income tax and the heavy thumb of the IRS is an important issue.
I don't accept the underlying barely concealed premise, which implies a certain Calvinist vicious austerity, that consumption is a vice that should be punished with punitive taxation.
The "FairTax" advocates haven't thought it through at all, and the more I think about the idea the more I hate it.
