alt Hacker NewsRight, there was clearly much more capacity for advanced education with the rise of technology (farming advancements, medicine, electronics etc) that started before WW2
There is something to the point about needing a correction in post secondary education and making university again a specialized place rather than the catch all default generalized institutions. Where 70% of the population tries to waits 3-5yrs+ to enter the workforce in exchange for lots of debt. A debt heavily incentivized by cheap gov backed loans, subsidies, credential inflation, and very profitable immigration schemes.
Sure, there are real issues with cost, debt, and credential creep, but that does not change the basic point: the expansion of education itself was a net positive for decades. The problems we have now come from financing, policy choices, and a labor market that shifted under globalization. Blaming education levels for broader economic or social trends just mixes up the cause and effect.
