Why will Nobody tell (most) College Students that MOST of what they are doing is a WASTE of TIME?

Because no matter how many times you post this rant, most of college is not a waste of time. Are a few people wasting their time? Sure. Are most of us? Nope. College sounds like a waste of time for you personally. That does not apply to everyone. And self-study in most topics won't get you a job. You need some proof you actually learned something. Just try self-studying medicine or astrophysics and see where that gets you.
