I could not agree more
So, let's pay the expats twice the money the locals get, ohhhh no, let's pay them three times as much, and give them our wives and sisters!
I do agree sometimes being an expat sucks! but it was our option, no one pointed a gun at us to move to a different country and we are welcome to leave at any time. If you are still there is because you like it, or going back is a worse option, companies know that and they DO take advantage. It is called globalization and free market. Or we don't like it when we suffer from it, but we love it when thanks to it we can get a cheap latte...
And if I remember correctly HK is not known for its friendly labor laws, so one has to ask, "why are you still there, mate?"
