This reward of an expat lifestyle that you talk about is the reason most people are leaving. It is not a true expat lifestyle. Trust me I grew up as an expat with both parents overseas; and living in Disgruntled Bay is not how I remember expat lifestyles to be. I dare say your 'humble 40 years'
as an expat has all been in Hong Kong. Then sir I am sad to say you do not actually know what an expat lifestyle is.
