Professor Holmes the problem is the benefits of NAFTA have gone to the few. The owners of capital pretty much. For those of us who must labor to pay our bills instead of cashing dividend it has been a disaster!!!! GDP is completely and utterly irrelevant if a LARGE majority feels they are losers and THEY DO! Nothing like watching Management pack up the whole production line and ship to Mexico so they can pay 3 dollars a day and get a tax write off to earn Mexico the undying hatred of the people whose jobs were shipped off. Nothing like here is 2 weeks pay so long. Retraining oh sorry that's your problem and your unemployment runs out in 3 months. You can talk GDP all you want the fact remains a large and increasing number of VOTERS believe NAFTA is a zero sum game for people who must work instead of sit in an Ivory tower. You and the rest of the economists look a GDP growth which is going to the top 1 - 2 % and the number of jobs never mind the fact the jobs pay considerable less then the jobs the companies got tax breaks to ship to Mexico. Either the facts must change read shipping decent paying jobs to the 3rd world and replacing them with Walmart and Mcdonalds must stop. Or you must convince the very very large number of losers it is actually a good thing for them. I don't think even Joseph Goebbels could pull that off. And if the facts or the perception don't change this country is going to elect someone who makes Trump look like a moderate.

Why is it Economist forget GDP is irrelevant to the working class paychecks are what matters to them?? You know the paychecks that have gone nowhere since NAFTA was signed while executive compensation and profits have sky rocketed. NAFTA may have someone but not the majority of voters.
