I think the established socialist terms are best, even if they require further explanation because our definition and understanding of “class” is the distinction between us and your average Republican. It’s the definition from which our entire understanding of politics flows. To a Republican “class” is a series of virtues you signal, self reliance by having a pickup truck, being a hard worker by having working man boots and not being college educated. A petit- or bourgeois man born with a silver spoon in his mouth can still be happily brought into the fold of “working class” so long as they get their hands dirty and don’t talk like “the liberal elite”.
To a Marxist, “class” is based on whether you have an exploitative or exploited relationship to production.
Definitely, but if the recent spike we’re seeing keeps going we should be well on our way to 80s and 90s levels by next year!
