I believe it all stems from envy. That’s also the basis for Marxism in all its forms (communist, fascist, nationalist). They want what someone else has and will use any means necessary to take it.
Really, all those railing against NAFTA and free trade would be very enlightened to read Friedman’s book “Capitalism and Freedom” and see just how the two are tied together. You really cannot have one without the other. You end up with some form of Marxism if you try...
Hmmmm Okay ... we tried free trade and what is sitting in the White House and who controls both of the legislative branches?
