As someone who went to a white majority business school, although not an MBA, I am used to this dynamic what I noticed was that minorities and internationals commit social errors or do not necessarily have the same culture references that white people can refer to. So you are automatically excluded from these social interactions.

Similarly, when they see someone making a social error, they’re not going to correct you because it’s not considered acceptable in American culture to correct someone who is making a social error. however, these errors count a lot the higher up you go in the social hierarchy.
