What I say in summary is that it would probably be better abroad for us, certainly for our kids, and at least we'll have had an adventure out of life!
I had always fancied living and working abroad but never had the money (from traditional Northern working class background). Me and dh always seemed to be getting pee'd on in uk, so no big attachment to place, quite the reverse. Disadvantaged backgrounds, victims of unprovoked violence, etc. every time we tried to do something to improve our situation something came along and kicked us in the teeth. Fed up of paying taxes to support those richer than us while we were struggling to eat, only to be told when our turn came that the boat had left, that sort of thing. Could only afford to rent in inner city areas, not worse, but not best despite now both being working professionals. As soon as we could afford holidays we went to Europe to see if really was more socially equal and better culture, and it was. As soon as had kids really wanted out - not watching kids go through same - so dh started looking for jobs. Went with first offer to get out.
It is difficult being a stranger in a strange land, not very welcome as immigrants, and there's a language barrier for us. But we are living in a nice house in a nice area without fights outside our front door, the kids go to a school where older kids play with them not rob them of dinner money. Much better education system here, I believe better prospects for jobs whatever figures the uk produces.
Uk has gone to hell in a hand basket for working people who have no family support. The government always went on about Victorian family values and that's what you're getting - if you aren't born into right family you are stuffed. We had nothing to lose, and have gained an awful lot. Now we just have to see if I can get a job here too!
