If memory serves, back in the "old days" of FR (so long ago now, I think I was still using my Uriel1975 screen name at the time), I used to be a die-hard Forbes Flat-Taxer who went round and round against you and "pigdog" and "CHIEF Negotiator" (RIP; but at least he is now immediately-present with Our Lord) trying to knock down the "Fair Tax" which at the time I believed would be disproportionately burdensome on the poor and working-class.
As I recall, you treacherously employed my own Libertarian sensibilities against me, posting Evidence from CATO Institute proving that my concerns were over-wrought. Faced with superior Evidence, I was forced (as a Rationalist) to concede the debate and convert to the Fair Tax position.
Well, at least it stuck. A "Fair Tax" Convert I remain to this day (allowing only that I think that the $2 Trillion-dollar Existing-Home market should also be included in the Sales Tax -- expand the Tax Base broadly enough, and I bet we could get the rate well below 23%).
Long time no see -- and good to be on the same side of things (this way, you won't have to convert me. Saves us both trouble).
Best, OP
Wow, that's encouraging!! Be blessed, my friend! I'm glad we made some headway- sometimes getting people to change their opinions on taxation is as difficult as evangelizing the Muslims! haha
