I think you make some really good points but you including work from racist author Ruby Payne was a huge red flag to me. Her approach to class is steeped in harmful stereotypes about Black and Latino people. In her book A Framework For Understanding Poverty, she basically equates poverty as a result of poor personal character, rather than systemic disadvantages. She writes dialogues using exaggerated AAVE and racist, stereotypical names. Basically her whole thing is that poor people are poor because they don’t know how to “act middle class,” and borders on eugenic ideology. I don’t think she’s a good example of how to talk about class, at least in the way you’re trying to foster.
