My friend is in Japan right now and we just had a discussion about how shame is a tool of social control. I was even reminded of the old 80's introduction of the concept of "toxic shame". Obviously a lot of Westerners have no shame and are proud that no one controls them and will declare it loudly to your face.
It happens in all multi-cultural/diverse settings, everywhere. This is a fact of life. Homogenous nations tend to be the safest.
