When the Common Market was founded in 1957 it was mainly a trading alliance with a bureaucracy set up to oversee it. Like any bureaucracy, it’s main mission is survival and expansion. And so, of course, over the years, the elites that ran it looked to gain ever more power, and they have been very successful.
It’s why the founders called for “peace, commerce, and honest friendship with all nations, entangling alliances with none.”
I find it extremely encouraging that Trump has embraced the exact same policy. It’s why he’s against NAFTA and TPP and TTIP. He made it very clear that he favors bilateral agreements, rather than monstrous thousand page agreements among many countries that end up superseding our own constitution and doing away with our sovereignty. It’s exactly how the european countries ended up where they are.
