In my initial short searches I did earlier, Antonio Gramsci comes up as addressing the issue of “cultural hegemony”, where art and entertainment tends to represent the dominant bourgeois culture, which makes a lot of sense. I’ve heard of Gramsci in passing, but haven’t read anything by him yet. I think it’s a good place to begin regarding a critical analysis.

Also worth reading is Camus’ short piece “Create Dangerously”, on the responsibility that artists have to challenge.

I agree in general terms, but Bernie is not the only “uncompromised politician” in the world. How many politicians outside the US can you even name?
