That is very similar to my "inner circle" of friends. They all have successful businesses or have successful careers here, but they all don't see a future for their kids to grow up here (i.e. Middle School, High School, University, etc..). But they all have stayed trying to make the most they can, and I think they would all leave once they've taken what they wanted.
Honestly, I would never let my kids go to university in Hong Kong. The quality is getting worse, and mixed in with all these political debates, it just really ruins the spirit of the university experience for a 17-18 year old kid.
