Plus the amount and quality of alternative learning resources is very high, at least in some fields. I know coding bootcamps get a bad rep, often justified, but at the same time my buddy went to college for a degree in HR and I went for STEM. He ended up hating HR, did a 9 week boot camp, managed to get a job, and after a few years of experience is in roughly the same place as me and is thriving. It took him a little longer because of the time spent in HR, but ultimately he ended up with the same skill set I did between the 9 weeks of intensive study combined with on the job experience. Meanwhile I got a broader education, but the majority of it isn't very relevant on a day to day basis, if ever.
It's a single anecdote, but between online resources and alternative training programs, it seems harder to justify spending tens of thousands of dollars on college.
