My work has offered me a promotion and a much higher salary if I move to Beijing. This would mean relocating my family, including my wife, who has a career in Hong Kong, and my two daughters, who are at school. I think it would be a good career move, for me, but my wife is reluctant to go, especially in light of the chronic air pollution in Beijing. My argument is that my new salary would exceed our combined salaries and we could move on after a few years. Is it worth the disruption, or am I just being selfish?
