While much of college is indoctrination, the washtowel rags are even worse. You cannot get much of an education reading the Asleep! rag, even back in its prime. Will you get credentials? Can you actually learn anything meaningful in science through these rags? What about calculus, which is mandatory in college? Or even basic chemistry, also mandatory? And, suppose I were to read them in German and take no other German. Could I get my German to C2 level using just these rags? (Or English, if my primary language was Spanish or something else.) Are these rags anywhere near the literary quality of Shakespeare? I doubt it.
With no practical value, no educational value, and no credentials, I would think the washtowel and asleep rags are worthless. Indoctrination or not, at least college gives you credentials. (Which are just about required for any meaningful jobs.) The Internet, while lacking credentials, does give you education and entertainment opportunities--that is where and how I got most of my German (between German language videos and books in German ordered using the Internet).
