Also curious what you mean by thinking of education as an investment being part of the problem. What is the problem, and why does framing education as investment contribute? Are you talking about purely financial forms of investment? Education is widely viewed as social, cultural investment by society, as well as economic investment, and this is widely agreed to be a good thing, isn’t it? At the personal level, education is also viewed as a career & future financial security investment, and this also seems reasonable, no? I feel like the most important investment my education bought me was the freedom to choose my career path over time. Had I not gone to university, I do believe my choices would be more constrained than they are today.
ther are a usually few general courses (civics, economics, etc) at every undergrad, but these are usually low quality, mostly useless, and absolutely dwarfed by the usual introductory classes (usual STEM for STEM, etc)
