teachers are laborers, not merchants
I’ve said this before: if education was really about access to information, then anyone with a library card could have skipped college well before the internet. The idea that the internet suddenly made education obsolete because it freed information from being hidden away presumes that information was kept under lock and key. But, you know, books exist and are pretty cheap and they contain information. Yet if you have a class of undergraduates sit in a room for an hour twice a week with some chemistry textbooks, I can tell you that most of them aren’t going to learn a lot of chemistry. The printing press did not make teachers obsolete, and neither has the internet.
