There are two main problems with the EU, both political.
First, the EU Commission has way too much power, and honestly wants to play dictator. Look at ChatControl: Voted down more than once, but the Commission just repackages and resubmits, with some dirty backdoor tricks, until they get it through. Parliament is not allowed to propose legislation, only the Commission.
Second, regulatory hell. The continual avalanche of regulations out of Brussels cannot be overstated. People make fun of the bottle caps, but those are absolutely illustrative of how literally everything is over-regulated. This is one of the main reasons that European industry is struggling.
The EU commission is just a way for national governments to launder their authoritarian desires through the EU. The commissioner for each country is choser by national governments. It's them pushing that shit.
The main problem with it, is that when you vote on national elections, typically you are concerned with local issues. Housing, healthcare, transportation, employment, immigration, etc.
Nobody is really thinking "who will this party behave on the EU level?" Then they do shit like this and hide behind "we have to comply with the EU".
> bottle caps.
Oh, the humanity! And the lack of bottle tops in the streets.
I'd move to the US, but your lack of regulations scares the piss out of me. And your cops, and your electoral system, overall crime stats....
Your first paragraph rings true.
