The “Brexit” vote by the “uneducated” British should be a wake-up call for advocates of ever-expanding global trade. To the Editor:If we believe the study quoted by N. Gregory Mankiw, there are two categories of voters: those who believe that global trade is intrinsically good (as advertised by mainstream economists), and the less educated and therefore “isolationist, nationalist and ethnocentric,” who are skeptical of global trade and outsourcing. object not to international trade but to trade agreements that are biased toward corporate interests, allow abuses of labor and the environment, and are unaccompanied by effective trade adjustment assistance for those American workers who pay the price for the increased prosperity that trade brings to the rest of us. In fact, how can it be logical to suggest that workers everywhere would gain today if international trade were curtailed, while continuing to support free trade within the United States? J. ErnweinMareil-Marly, France, Aug. 1To the Editor:I wish that N. Gregory Mankiw had addressed a fact that always has puzzled me: Why does interstate trade never come in for the same attacks as international trade?
