I partied my way through an easy major with nothing to do with my job. The people who didn't have no "superpowers" that I don't. The degree is a bunch of status signalling bullshit.
In short, soft skills. It depends on your degree I guess. In an MBA or education program, the distance between try hard and slacker is narrow. In more abstract less career oriented programs, the difference on critical thinking and comm skills is huge. If you can't imagine how deeply studying great works and thinkers improves your mind, that tells me maybe you missed something big.
