In my neck of the woods I've found that the real MAGA true believers are usually upper middle class and furious that they're "still" in the middle class. They believe that they deserve to be better off than they are and are almost always racist to the point that they yearn to be able to have enough to separate themselves from "others."
In actuality, they *should* be mad at the oligarchy that's always "above" them, that's the class they want to be in and can never achieve, but instead they're wrapped up in being mad at people who don't look like them or share their self-described "conservative"(read: mostly racist) beliefs.
@BE This is an old US pattern. Get the middle to be mad at "those people" while the oligarchy rakes in the proceeds. Created in the 1600s by Virginia planters.
Was how things worked when I grew up in Louisiana, which has always been an oligarchy.
