Personally I learned absolutely nothing from my major, but I had mandatory units in law and accounting which I thought annoying at the time but have proved extremely helpful in my later career.
I’ve done some mentoring of Uni students in recent times and it seems they’re even less prepared for the workplace than I was on graduating - they’re not learning anything that will be useful and they’ve not had practical experiences to give them a grounding that employers would expect.
It’s a shame that it’s gone this way because we do actually need to educate people in some really complex things nowadays but the system is so captured and broken as to be largely useless in this form.
