If the sales tax folks would just stick to real advantages of a sales tax they would go a long ways. Instead they try to sell this tax as all things to all people. The biggest advantage being that it would strip the income tax out of our exports and add sales tax onto our imports, giving the US a well needed trade advantage. Of course that means the price of imports will rise, but that is the price we would pay. That is the one real advantage of the sales tax. Most of the other claims are gross exagerations and misrepresentations that turns most people off.
"... That is the one real advantage of the sales tax ... "
in fact is not correct as it undersates things since those are actually two advantages (helping exports and also taxing imports) and not THE advantage. There are many other advantages and they have been discussed many times. the fact that you do not agree with and will not accept many of them changes nothing ... you're welcome to your opinion.
They are still many advantages.
