One simple story about the 2024 election is that college educated people voted for Harris and the rest voted for Trump which is the big takeaway of a conversation Ezra Klein had with a pollster.

Jacobin has the problem that Marxism is something that appeals to highly educated systematizers, e.g. the college educated. The reason why the U.S. doesn't have representation in the fourth international is that in the 1980 the leaders of the Socialist Workers Party, inspired by Castroism, thought that their college-educated cadre ought to "go native" in workplaces and it was something they didn't want to do.

Marx himself said that the Labor movement would lead to the emergence of real working-class leadership, which it does, but the decline of unions means the decline of that pathway. (e.g. when my Uni hired non-union glaziers to put up glass for a building the glaziers set up a 12-foot high inflatable rat; maybe it makes a good image but that's not intellectual; accept his ideology or not, but Marx was one of the founders of contemporary social science and very much an intellectual.)
