been thinking about aristo/bohemian/lumpenprole as a coherent axis defined around common cultural traits (decadence, cults of action?) against a rivalling stability-oriented gentry/bourgeois/prole line
I think the concept you need to tie this together is “belief that the formal rules make sense and that you will be rewarded for following them.”
I once wrote much of a very long essay about (approximately) this, but lost momentum before it finished. Short-short version: aristos and proles are both keenly aware that in fact life is a political jungle where success is defined by allies and resources and risks-that-pay-off, the spiritual essence of the bourgeoisie is “thinking that the world is basically an extension of school.”
