It is talked about, but maybe not to the extent that it could be. For obvious historic reasons, race and class are highly correlated. I think this causes certain class issues to disguise as race issues and vice versa. To be clear, both kinds of discrimination exist, both are terrible. But people are sometimes bad at separating correlated variables intuitively. And, how do I put it, the social sciences don’t have the reputation to always use the most statistically sound methods.
Also, people discriminate so much on class that it may not be an advantage to be of a higher class.
I can’t count the ways people invent criteria, such as “street cred”, to prefer some people upon others. “Humble”, “son of worker”, “comes from the hood” are other criteria people use to justify unfairness. Ironically, streed cred is so cheatable that the only ones we let down are the actual middle classes with strong sense of work, because they pass as supposedly rich. The middle and higher classes end up with heaps of resentment which harms society (I remember events such as a girl telling me “I ruined your reputation at school but I was wrong, you were the good guy. Oh sorry for your high school btw.”)
