This exchange summarizes my opinion of much - though not all - university-level education:
Doug S: Remember: the job of a university professor is to do research and bring in grant money for said research, not to teach! Teaching is incidental.

redired urologist: So why do the parents pay $40,000+ annually for this type of service?

Doug S: In most cases, it’s not the education that’s worth $40,000+. It’s the diploma. Earning a diploma demonstrates that you are willing to suffer in exchange for vague promises of future reward, which is a trait that employers value.
So Dilbertesque... but - like Dilbert - generally true.
