What they really need is a way of reforming these things (namely the EU), instead of it being a "love it or leave it" type of affair. This is one of the big problems with human-created bureaucracies: there's no easy and effective way to reform them, so people end up either abandoning them (e.g. Brexit, various independence movements or revolutions) or they become usurped by some better competitor (e.g. IBM being pushed out of the PC business, American automakers losing to foreign competition) or they end up collapsing (e.g. DEC being split up and sold in chunks, or the Roman Empire falling apart).

It seems to be a constant that larger human organizations are simply impossible to reform effectively, so we're stuck with chaos. I don't think there's a solution for this, short of genetically-engineering humans to work better together, or else we would have found it over the past couple of millennia.
