On average, a dollar has the same purchasing power pre and post FairTax.The post-FairTax value of a pre-FairTax dollar depends what the Fed does. Kotlikoff say it "seems likely" that "the Federal Reserve fully accommodates the introduction of the FairTax and permits consumer prices to rise by roughly 30%." If consumer prices rise by 30%, then a pre-FairTax dollar would be worth $0.77 post-FairTax.
As far as your references to Kotlikoff, you and I know you have been discredited with your interpretations of those references numerous times on FR.This is where I ask for links to the "numerous times on FR" where I "have been discredited with [my] interpretations of those references" and you refuse to produce them. It's an old and tired FairTaxer game.
For newcomers, here’s a link to the actual Kotlikoff study group where you can digest and form your own perspective: http://www.fairtaxblog.com/20061002/kotlikoff-study-23-fairtax-revenue-neutral/For newcomers, this is a link to a blog, not "the actual Kotlikoff study group." This blog entry simply discusses and links to the exact paper I referenced.
The blog contains comments and links in those comments from many studying Kotlikoff’s estimates. They are a group. They are the Kotlikoff Study Group because there is no formal group that studies Kotlikoff’s estimates.
And linking to his paper does not make you any sort of expert. As has been shown before, your intepretations of his paper and other materials concerning the FairTax are deceptive. You care about only one thing, disrupting FairTax threads with points taken out of context and designed to cause confusion. Witness your lame attempt in post #28 and my response in post #39.
