You can argue statistics any way you wish. The reality is that the present package is barely adequate.
For a single person, it is livable. You don't really care that you live in a 400 sq ft shoe box. You have enough to enjoy yourself a few nights out a month. Can barely save any money.
For a married person, it is questionable. You may accept it because you are 'trying to establish your career'. Your wife however will feel claustrophobic within 6 months, and constantly be bitching to you that she never gets to go anywhere and hates the apartment/chinese/weather/etc. You will save a little perhaps for a rainy day fund.
For a married person with children. Welcome to hurt city. You will spend all your time dealing with a desperately unhappy wife, confused children and a very fragile home life. You will be crippled by the cost of schooling (if you can even get them into one), your wife will hate that you have no money to do anything, your kids will resent you because you can't provide them the life that many of their classmates enjoy. You will save nothing for the future.
There is not a recognisable package in HK that addresses the issues of retirement, medical and long term savings. CX expects you to have just enough to get by. After that, they really couldn't care less about your family's happiness or your need to plan for the long term. That's the reality.
If you come over, don't bother complaining to your colleagues how 'tough you have it'. There is plenty of info out there, so it's way past time where ignorance is an excuse.
