The grass is rarely greener. every country has it’s problems, generally you are just swapping one set of problems for another.
And I agree with PP, expats in other countries tend to spend their time reminiscing about “home”.
FWIW I’ve nothing against emigrating, have lived abroad myself, but people do seem to live under the illusion that moving somewhere else is going to solve all their issues and suddenly make life great again.
Yes financially you could be better off.
In terms of lifestyle you could have something different.
But you are potentially sacrificing your relationships with family and friends to get those things.
Not seeing your family for years at a time for instance. People say they will visit but they tend not to, and so you end up having to come back here and spend two weeks catching up with people whose lives have nothing in common with yours any more.
The relationships the kids have with grandparents is totally different, because they don’t really know each other. they’re just the fun people they see every few months if they’re lucky.
And zoom is most definitely not a substitute for any of that.
If you don’t have a close relationship with your family then it’s not an issue.
But if you do then you need to realise that moving means that relationship is going to change irrevocably.
I grew up abroad, and I wouldn’t change that experience for anything.
But ironically the country I grew up in has far more problems than the UK ever will.
And most of the expats I know who are still out there would love to move back, except they can’t afford to because the exchange rate is so horrendous.
