This one here slaps your premise to the side. Black Elites want to talk about class all the time. Black people collectively, all of us, are ready for the caste system to be dismantled. Roediger uses DuBois' work to explain it too. Your analysis hardly works for me though there is a class struggle within Black America but that is the product of "whiteness" not class per se. White class. Nixon used to say - the more Black middle class people, the better. He wanted to say, see, it's their own fault. They are stupid and inferior. It is classic white supremacy at the highest levell of government. I could name dozens of examples of this class struggle but those Black people remain stuck in that caste system of whiteness. It is not just monetary either. Should the CBC in Congress change its ways? Sure. Did Obama sound silly lecturing Black people when he was in office about their moral failings? Yes, he did. But even if they shifted their efforts totally to class, that won't change the caste system unless "whiteness" is eliminated from American life in total. DuBois butchered this approached in Black Reconstruction, maybe the greatest book of sociogical research in American history. Imagine, DuBois, one of this country's greatest thinkers and writers is barely taught in the schools, just like Howard Zinn. That is in itself the caste system we live with.
