It seems that poor WTFAW is getting jumped on by all you happy people who relocated to HKG. We all have to to look at our own personal situation and I for one would agree with him. The decision not to uproot your kids is an unselfish one. Whether or not it is worth it to move to a different country (or even a different part of the world!) is a difficult decision to make. Yanking your kids away from friends and family, especially at a sensitive age, is seldom the best solution (speaking here from personal experience) just to get a better job.
For all of you happy pilot families in HKG or wherever, I'm happy for you! Really. Nothing beats home in the long run though....
