Like a few others have said, college is what you make of it.
If you go there wanting nothing but job skills, there's a good chance you will leave there without much else to show for your time. But it's also possible that you will encounter a professor or two who will open your mind to quite a bit more, in spite of your best efforts to resist. It's much better to show up without so many specific expectations, and see what develops.
Unfortunately, more and more students are having to work a lot of hours at a job and/or commute to class from home, due to financial necessity. That reduces your chances of getting more out of college than the basics. They aren't getting the complete experience.
I find it sad but not surprising that so many people who haven't been to college think they know so many reasons why it is worthless. This is a logical "catch 22" situation. If it was possible for everyone to fully understand the value of it without going there, then nobody would need to go there.
Sometimes, it is years later when you are able to look back on a particular educational experience and see what you gained from it.
Professors in various departments do have their own distinct perspectives, agendas, and biases. That's one of several reasons why you're required to take classes in a lot of different subject areas. Successful people have to learn how to deal with that kind of conflict and complexity. You learn that by doing
it, not by reading about it. Also, the whole body of knowledge you come away with is greater than the sum of its parts.
This is a hard subject to talk about, because it's easy for some people to have the reaction, "You're saying that you're better than me, because I haven't been to college." And if I say to them, "No, I'm not better than you", then they can respond, "Then you didn't learn anything worthwhile in school." That isn't a useful conversation. It leads away from the main point.
Most importantly, what education gives you is a better mental tool box. I like that analogy, because everybody knows a tool of any kind can be used for something good or something bad, but you can always do more with better tools. Travel and work experience add more tools to your box. You can never have too many.
