They&#x27;ve proposed that, but as far as I can tell it&#x27;s less of a serious proposal and more an instance of an &quot;overcoming objections&quot; sales tactic. I don&#x27;t see how a flat sales tax can achieve revenue-neutrality (itself a major selling point of FairTax) while also offering a large enough &quot;prebate&quot; to avoid being enormously regressive in practice. Considering the misleading nature of a bunch of other FairTax claims [1], I pretty much consider distrust to be the only tenable default position with respect to anything else they say.<p>[1] <a href="http:&#x2F;&#x2F;www.factcheck.org&#x2F;2007&#x2F;05&#x2F;unspinning-the-fairtax&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.factcheck.org&#x2F;2007&#x2F;05&#x2F;unspinning-the-fairtax&#x2F;</a>
