So I looked, and yeah it's pretty well described:
https://en.wikipedia.org/wiki/Power_distance
https://en.wikipedia.org/wiki/Impact_of_culture_on_aviation_...
So, my question to you is, given that the above is pretty widely recognized, why is it racist to merely describe an experience with this cultural difference?
Saying that someone grew up in a culture that values a certain type of academic education and achievement is different than saying they have those characteristics because of their racial genetic heritage.
It's also one thing to be aware of cultural trends and differences when designing multicultural systems to function well. It's another to project cultural trends onto individual people since the variation between people in a culture easily dominates the variation in the averages between cultures.
Of course, nuance like this rarely makes it into common discourse, which often does end up just being racist.
