I know you’re just venting OP, but some thoughts:
I live in a European country, I’ve been here since before Brexit though and have worked abroad all my adult life. While no country is perfect and the UK has its good points, I wouldn’t swap it for where I am.
Yes Covid hit hard and the cost of living has gone up a bit, but the price rises are not as extreme, and it’s just not like in the UK where everything feels really severe and miserable, like everything is on a downward spiral. I completely understand where you’re coming from.
Having nicer weather, food, and most people being friendly and kind makes a big difference! If you’re seriously considering it then there may be a way, it depends on the country obviously.
Through my work I meet loads of people from the UK who are thinking of moving abroad, and I’m often in touch with legal professionals who advise them on the process, usually specialising in eg. tax, visas, property… With your background is that maybe something you could look into?
In your position I might also look at moving to a different part of the UK. Not sure if that appeals. Good luck whatever you do!
