It's a different culture, with different morals and ethics. Yes, points east have imported many elements of western culture over the years (style of dress, music etc etc) but this kind of thing has been intrinsic there for thousands of years and it won't change easily. It seems unacceptable to us westerners but it is much more "normal" there.
I am minded of those expats that head east for career opportunities and then complain bitterly that they are treated like slaves & with zero respect. What did they expect? Working within a company owned and managed by "locals" will incur a "local" employment experience, and it's their trainset or rather aeroplaneset, so they rightly call the shots.
Maybe some people should be more interested in preventing "western" standards from being slowly watered down at home by conflicting cultural values and globalism, rather than worrying what happens overseas.
