The reality is that most of the UKs problems were not because of the EU before and are not because they left the UK now.
At the worst times, you could phone to thirty pharmacies with a relatively standard recipe (Augmentin etc.) and be turned away everywhere.
Been there, done that.
That said not all the good stuff actually was caused by the EU either. I'd recommend watching Yes Minister but apparently that will get you put on a watchlist these days... https://www.reddit.com/r/ukpolitics/comments/1153smh/yes_min...
The fact is politicians at all levels including EU take credit for things they didn't do and try to ignore the fallout from things they did. All the while blaming the voters. Mainly because changing public perception of policy choices takes time and effort and they have limited of both and tend to want to focus on things they actually care about.
Sounds precisely like Czechia right now.
edit: apparently this is a controversial statement

My personal suspiction is that UK citizens were mislead about the consequences of leaving but, hey, democracy is about taking decisions with incomplete information. People have spoken and their decision is sacred. I wish the UK the best luck and it's with sadness that I believe they will need a lot of it.
Besides their xenophobia and racism, at least the Nordic countries are closer to informed voters.
In the EU as a whole it's slightly higher because of the East countries (Hungary, Romania, Latvia, Estonia, ...) where inflation is crazy high because of their dependency on Russia for energy.
UK is in the very West of Europe, not East, and not reliant on Russia as East countries are. The economic impact of Brexit has just been significant, as it was supposed to be. Everybody knew it would be. Brexit was never about economy, but mainly sovereignty. That's a legitimate trade-off, of course, and many in the UK prefer to be a bit poorer in exchange for less dependency on their neighbours. I respect that. But it's important not to fool oneself thinking that leaving the highest economy in the world (EU economy was bigger than US' before UK left) was going to be good for the UK economy. That's just nonsense.
