For me it’s simple.
EK package + merits of living in Dubai > CX package + merits of living in HK + sunk cost of relocating family from HK + sunk cost of seniority in CX.
So let me get this straight...you are not willing to make any sacrifices to better your career, you simply want to stay in your own comfort surroundings close to family and friends and receive the same package that is entitled to those who made the sacrifice to live abroad to better their career.
You think Hong Kong is an easy place to live for most expats...what Dubai is to you, Hong Kong is to me. I stay because of the package, take away the expat benefits and I'll be out of here faster than Adolf Chen can hand out Lai Sees.
