Is There Something About Korean Culture That Produces These Outcomes?

I wonder what cultural interventions people see that are possible that are not absolutely authoritarian and brutal in the sense of raising someone like, you know, let's say an African American child as a Korean child. I don't understand maybe nudge people in the direction of being more Korean but it's a sounds a bit brutal to me. If we were to make that discovery, then it would suggest that we can do that culture is much more powerful than than we thought. finding out what it is about Korean culture that produces these outcomes would be the most important social scientific question.
