So there is nothing else at college to learn but what you call nonsense, not a single thing but nonsense as defined by you?
Well, I didn't write
that. But I'd say that a lot that is taught is nonsense. I'm not against education. I've much in favor of it. Yet, education to "broaden our minds" can be obtained readily elsewhere, without going into debt for a useless degree. Want to learn a foreign language? Curious about the history of this or the history of that? Would like to brush up on your math skills or learn more complex math? Interested in 17th Century French literature? Don't need college for any of that. In the times we live in there is free or inexpensive access to a bounty of information. Piling on debt for a degree showing you're educated in the "unmarked whiteness that incorporates certain previously stigmatized transgender bodies" doesn't make you smart. It makes you dumb.
Why would anyone be interested in 17th Century Literature by random chance? Only after learning enough about it or related things via formal education where others direct you to what is interesting and why are most people interested in learning more about it or learning about similar subjects.
Set novices loose on the internet to learn about a topic and decide for themselves what to read and most of them will come away dumber than before they started, chock full of misinformation. In fact, among the many things one can learn at University is that there are formal experiments showing that this is the case.
It typically takes a combination of generally above average smarts and some level of prior knowledge of a topic, for unstructured unguided self teaching to be effective.
The exception to that is if one is just trying to answer a very narrow specific question with a simple clear factual answer, which is NOT the kind of learning that college courses even in the hardest sciences are or should be about.
In addition, while too many classrooms are poorly run, the context of a well-run classroom provides participation and exposure to discussions shown to increase deeper understanding of complex topics. It isn't simply a matter of hearing others "great" ideas. Even hearing bad ideas about the topic your are trying to learn will generally improve your understanding, if relative experts are there to shape the discussion, highlighting flaws in ideas and helping students construct better ones without merely telling them the best answer. Well designed classroom and homework activities serve a similar function. Tons of research shows that students gain a more long-lasting and nuanced understanding of topics by constructing the answer rather being told the answer. Plus, developing student's skill in how to acquire knowledge and construct an understanding is as much the point of college classrooms as teaching them what is already well known and accepted in various fields.
Finally, there is a motivational component. The important goals satisfied by college are all long-term with the benefits being diffuse, indirect, and spread out across the lifespan. It is far too easy and too likely that the vast majority of young adults (or any age adult) without the incentives class enrollment brings would find reasons not to sustain the kind of focused attention on a topic over and extended period that is required for notable progress in understanding. Reading an occassional article here or there when you get around to it, doesn't cut it. Thus, even among the small % of people with the intellectual skills to learn just as well on their own, few of them actually would do what is needed to make that happen. College makes it far more likely that more people who can learn actually will learn.
All that said, sure, for some people, academic type college where the goal is beyond learning specific skills for a specific trade is a waste of time and money, because they lack the more basic knowledge, skills, and/or motivation needed to take advantage of the college learning contexts I described above. For example, it is one thing to need motivation of not failing a course to get you to do your assignment. But that isn't going to be enough if you don't care enough about getting a failing grade and/or wasting your or others money.
