It’s not even “bias.” It’s an odd form of white supremacy that views whites as above having material interests of their own. “It’s okay to be unfair to white people because they don’t need it like we do.”
I make the clarification because I’ve noticed it even among people who don’t have in-group bias. My mom quite dislikes other Bangladeshis, but only slowly realized over 30 years of living here that there are white-majority parts of the country with real economic challenges.
