I don't doubt this.
I also have little doubt that BOTH Trump and Hillary are liars when it comes to their trade policies. They both know full well that free trade has made the American economy more robust than any other economy in the world, and that, thanks to globalism and our lead in it, we have the greatest standard of living in history.
It's just that politicians need a scapegoat for those who are left in the cold by technology and globalization, so they bash trade deals. Globalization and technology are both forces so irrepressible that no government can reverse them, so I am not worried. I am concerned that my party's grassroots voters now seem to embrace protectionism. Big mistake.
