Nothing so complicated as all that. It seems to be genetic and immutable in Oriental cultures : Saving face.
That's why I would never trust my life, or even my health, on a "professional" Oriental. This MH370 business typifies the entire problem. It is childish, it is primitive, and has no role whatsoever in the 21st Century.
I never have, and never will avail myself of any Oriental transportation company. In the air, on land and on the sea.
I agree with your assessment of certain Asian cultures being problematic in certain capacities, Korean pilots being the most glaring example, but I doubt that this problem is indicated here.
