Yes, he should just dedicate his life to toiling away at a problem he can't make an impact on while telling his kids and wife that he's very sorry that he can't give them a significantly better standard of living because he needs to help fix England.

No, I was miserable in the UK - I have better options elsewhere. I do not care enough about the UK to give it my life. The culture is locked in by hundreds of years of history, and a vast, vast majority of people like it the way it is.

Staying in the UK for me is like staying in an abusive relationship or a job you hate. It made me deeply unhappy, so instead of complaining and bringing my friends down I found a life to love overseas.

Fair enough. All any of us wants is happiness.
