Lol, they're all mixed up together along with many other motives various groups have for supporting pretend free trade agreements and the globalist goals of open borders and the erosion of national sovereignty. - The European Economic Community preceded the EU. The globalists proceed in stages and can use all the useful idiots they are able to hoodwink into their cause, wittingly or unwittingly.
You've spent too much time reading econ books and not enough time observing the world as it really is, and the behavior of individuals and nations as they really are.
Free trade and free markets work pretty well within the USA, but not so much on an international basis. We finally have a president who'll stop the pretense and resist the goals of the globalists, and deal with the world as it is for the benefit of US citizens.
We’re done and the American consumer will pay for the Trump tariffs.
Hope is was a helpful discussion for any onlookers.
Good luck.
