While I like that you try to show the situation(s) may be more complex than seen at first glance (which is true for any situation anyway), the sheer number of situations should easily explain there is one or many global causes for all these.

I watch the video of a thai native going back to Thailand to make a restaurant and his experience is the same : paid the workers more to get them "committed" but they have this culture of "good enough/it's not important".

You cannot expect civilizations with millenia of divergent cultures and climate to have evolved with the same cultural/traditional habits.
