Back where I'm from, things aren't looking as bleak as they are in the UK. I found that comment amusing really. The assumption that since Britain has historically been wealthy and a one of the better places to live, if things are not looking great there, they must be so everywhere or something.
In eastern Europe it's common to see young people building their own houses in rural towns near the big cities. They earn less money, yes, but they don't waste 50% of it on rent.
It's a different way of survival.
Now there's a western-centric statement, if ever I saw one. Why do you assume "the poorer EU countries" are like the west, only worse? Other replies give more nuance.
What’s really helping, for now at least, is that housing is still relatively affordable (with the exception of Cluj, a very IT-focused city). If that housing affordability were to disappear then, yeah, the optics would definitely change.
