i'm not sure doing away with them is the right call. maybe being more realistic and limiting the numbers enrolled. look at the ones mentioned above (early childhood education and human services and community organization), they're all necessary for a healthy society, and do provide an opportunity for gainful employment, just not for as many as are enrolled. same for history, writing (non-journalists) and art degrees (my wife is artist, self employed, does ok).
i can't think of many degrees that don't have a potential for gainful employment, though some (many?) are limited opportunities.
as a society, we need to be honest with ourselves, and stop telling ourselves everyone should go to college. no, they shouldn't. but we'd also be doing ourselves a disservice to completely remove those majors. we need to start limiting our student populations overall, and specifically within those specialized, but not in demand, fields.
I was nodding along thinking "yeah, yep, yea!" but then recalled conversations in my field. That there are just too many physical science majors, too. At least too many who choose graduate school for the number of good jobs out there. To the extent that, on one hand, maybe the problem is that far too many kids are enrolled in college. Full stop.
However: While it is jarring how many students earn physical science degrees but end up working outside their dream realm, too often just to behave like pipetting robots, there is a counter-benefit:
Perhaps no more at any prior time in human history than now do we desperately need a human population with scientific literacy. This is a rapidly growing era of scientific revolutions that need to be consistently parsed from misinformation. Even or especially by non-experts.
And no matter what side one's opinions originate, when it comes to hot button topics (like cloning, evolution, anthropogenic climate change, stem cell biology, vaccines, GMO foods), society can only benefit from maximizing its skills of emotionlessly/methodically reasoning through things scientifically.
I'm now curious of the break-even point there, in terms of societal good. At which point, for example, do the societal benefits of a thing like scientific literacy outweigh the societal damage of this many people finishing in careers they feel are beneath their level of training?
