On a related note, I'm currently watching this fascinating documentary (🇫🇷) on the EU, its architects, the motivations for, and the implementation of the Euro. It's quite long, but worth it, if you understand the language.

It reveals quite well how the EU was engineered to weaken national democracies by depriving them of their political and monetary sovereignties, and centralise the decision making into the hands of unelected powerful figures.
