Over at Revealed Preferences, I suggest that the right abandoning trade shouldn't be so surprising to globalist conservatives. After all, support for trade on the right has been brittle for some time, and there's been no demand that it be deepened within their ranks.
Either trade is always positive sum and worthy of support, or it is not and it should be analysed and managed. The former leads us (and nearly all economists) toward a presumption in favour of free trade, while down the latter path lies a presumption of protectionism. There are many examples that could have warned conservatives they were on that protectionist path...
Again: either trade is positive sum, or it is not. Conservatives and progressives have together hollowed out the support for trade that would have explained to them whymarkets are effective, and a trading world is a freer, richer, and more peaceful one.
