Anyway, I wholeheartedly recommend reading Henry George's "Protection or Free Trade"[0], which both identifies why free trade is the right way forward, but also identifies all the suffering it is causing today. (The chapters "The real weakness of free trade" and "The real strength of protection" are amazingly insightful to what's happening to Trump's America.)
