I read an article a little while ago where someone recounted their academic career in Physics. What really hit home was his retelling of a class in undergrad where his professor (paraphrased here), "What you learn here really isn't physics, and most of you in this class aren't smart enough to learn physics." He got his PhD in physics, so it wasn't just him giving up. Everything I look at seems to add up to that statement across multiple disciplines. We place such an emphasis on academia which really teaches almost nothing useful to a career, etc. to the majority of people. I don't use my degree at all.
