Jordan Weissmann, Slate: Bernie Sanders, it is often noted, has never met a free trade deal that he liked. But in his recent interview with the New York Daily Newseditorial board, the senator from Vermont outlined the trade terms he might find acceptable. His statement should be absolutely chilling to the developing world. “And what fair trade means to say that it is fair. It is roughly equivalent to the wages and environmental standards in the United States.” With those last few words, Sanders has effectively written off trade with any country that is not already rich and prosperous — which is simply inhumane. What I can’t tell is whether Sanders simply doesn’t understand this, or doesn’t care.
