In college, my SOC101 class had a chapter on Karl Marx, my PHIL150 class had a chapter on Karl Marx, my POLS200 class had a chapter on Karl Marx, and in my dual minor my ECON350 class had a chapter on Karl Marx and my FILM300 class had a chapter on Groucho Marx.
I'm not sure how that's all relevant to this thread, but it seems somewhat profound to me.
That's pretty typical. Marx has always been required reading for Sociology and Political Science majors.
Pity they don't also into details of the debunkings.
It's better than people assigned Freud in literature courses.
