The vanity poster thinks he knows more about the Constitution and federalism than Levin and Rush. What he is proving is that he knows less about the 999 plan than even David Gregory - which is to say, he doesn’t understand sh-t about it....
In defense of the poster, did you read the article? It appears that in fact Herman is not clear in his article about the difference between a VAT, the Fair tax, and a national sales tax. What Herman appears to be suggesting in one of the nines in the 999 plan is in fact a national retail tax which he seems to deride in the article, despite it being part of the fair tax.
ditto.
