If the OP can share more about their role that'd be helpful. Hopefully I can offer some guidance as I've been in the recruitment industry for almost 15 years, 1st as an agency headhunter and now internal HR in industries such as finance and engineering
There are some industries where the salary is lower than others, there can be entire threads/debates on this but it can be due to numerous factors such as specialist skills / demand / competition
If you're in an industry where the salaries are low, I'd say Hong Kong is one of the best places to switch careers and reward those entrepreneurial types starting their own business
Remember, it sounds obvious but if you're working for a company it's not their issue whether you're paid what you term as a good salary. They would ask themselves more the question of can they hire someone else to do your role at that level of salary
