A source for reasoned speculation of how Congress would manipulate a sales tax scheme? No, and I don't have a time machine either.
LOL!

I am so glad you admitted that your scary scenario is "speculation". What about precedent? I believe that there are about 45 states which currently have a sales tax and none have been added within the past 15 or so years, if memory serves. So how many of the state sales taxes have morphed into the kind of monstrosity that you have forecast for a national sales tax?
