There is no credible evidence showing that "free trade" benefits countries more than it harms. Examples from economics textbooks and the claims of "economists" do not constitute evidence.  Moreover, there is no such thing as "free trade" practiced anywhere in the world today.

I will concede your point on the "proper solution".  The problem however, is that not a single government has done this. They're had to close to 30 years to "compensate the losers" and they've done nothing and continue to do nothing.  Even Little Potato, for all his grand speeches, does nothing.

Economics has proven to be nothing more than a sham masquerading as a discipline. It's practitioners are con men, charlatans and modern versions of witch doctors.  There is no need to pay "economics" or its adherents the slightest bit of attention anymore.
