Imagine seeing American wealth increase dramatically over the past several decades, see tax burdens drastically reduced on the top 0.1%, and see almost all of that drastic increase in wealth go to that 1%, and not be able to come up with a solution other than “well, against all evidence I think trade is zero sum”.

And worse, your solution then is tariffs, which are little more than a sales tax which are disproportionately paid by the poorest.
