I would say that people are being introduced to patterns of behavior at very early ages where it is near impossible for the parent or local community to correct because it's happening at such a scale where it's hard to mitigate. That's the ugly truth about "normal", normal is never objective. Normal is always a function of how many people are doing it. If most of the world is dysfunctional, it will never be assessed as a dysfunction. It will be seen as normal.
