Free trade works in the USA between the several states because the federal government enforces thru law a level playing for all the states. For free trade to work globally a global government enforcing a level playing for all nations would be necessary. You simply can not have real free trade between nations without a multinational government enforcing multinational laws. Free trade means given up our constitution and our country for some TBD multinational entity.
Is that another example of Reagan's senility? Starting to add up, now.
