>>while the fact is that everything worked pretty well before the EU
I don't know where you're from, but as a Pole I do not share this sentiment at all. Seeing the EU flag displayed everywhere makes me proud to be an EU citizen and it's a great thing to see.
If I was from Poland, I'd feel the same. Here in Czechia, it is a lie - this country worked well on its own. Membership in EU is great, but acting like there wouldn't be schools and public parks without EU is not.
Who is acting like that? The main criticism I have seen about EU funding is that it only gets allocated to the "easy" projects like renovating a park or some information board. Not that such things would never exist.
However even that is not true as the UK is finding out, as we are now scrambling to fill the funding gap that EU programs gave to anything from universities to farmers. All this while our corrupt government hands £37 billion to their corrupt friends for COVID "track and trace".
