My mom worked as a university professor, then advisor, and what she said about college was “it just shows a prospective employer that you can follow rules and commit to doing something for a few years and follow through on it. That’s why they want the degree. Also cuts down on applicants, fewer to sort through.”

So, from someone on the inside, she didn’t think the main reason was education, in terms of specific jobs. I know in accounting I don’t use so much of what I learned and that’s a pretty specific degree. Anyone with a mind for numbers & systems could be trained on the job to do what I do.
