The key is to incorporate both socioeconomic inequality with marginalization issues – because ultimately, all marginalization is socioeconomic inequality. That's one of saddest aspects of this division – the most vulnerable white identity poor still rank among the marginalized.
There's an old political cartoon, from the era of The Great Depression, I believe. In that cartoon, there's an obviously well-heeled robber baron type at a table with a white American and an stereotypical-for-the-times foreign immigrant. The robber baron has taken all but one a pile of cookies from a plate in the center of the table. The speech bubble above his head tells the white American that the immigrant is trying to steal his cookie.
That's America's white-identity poor. It's exemplified in how they sop up the proven-from-his-own-mouth crimes of Trump. The man as being repeatedly indicted in large part on his own words said to his cultish following. He openly tells them his crimes, calls it a witch hunt, then tells them "they're coming after you." And, they lap it up.
