People always talk about taking a pay cut, which in some cases can be worth it. But is it possible to live off it depending on were you go?

So, I made a career jump to being a Field Service Technician (Help Desk Teir 2) where I make 78k which is above average for that field and where I live. However, when I come here I see a lot of talk about taking a paycut when making a move. For me personally I'm willing to take a cut for a better QOL, though I know this position pays badly in other countries. I also know that even though it's a big cut, in some places it's sometimes relative. Like for example if I moved to say the UK where suddenly my 78k went to 35k-38k. Would it be enough to pay for a flat for myself like I do now where I currently live? Again just an example, not interested in moving there. Where I live right now it's still difficult with this amount.

So, I already have an idea of the places I want to go, and I'm currently up skilling and getting education part out the way, but this is just a general question.
