The problem with the reliance on scholarship to broadly promote globalism over protectionism, is that scholarship doesn't address the correspondent inequality, market constriction and monopolization that goes along with global trade. GDP and the avg price of goods don't pay the rent and keep private dairy farms in business. The economic benefits of globalism are vastly funneled to the wealthiest. We can't use 401k and retirement funds as an excuse to blanket fuck over blue collar and rural citizens. On top of that, it's dishonest to portray a liberal protectionist such as Bernie to be completely anti-trade. A shift towards protectionism in this current economy is a reasonable reaction.
