Later on in the article, he says that at around Thanksgiving, they start coming to class in their PJs. I can attest to this. My brother, who attends a private college, was quite horrified to see people flouncing in in slumberwear and slippers. He said that they might as well replace their desk seats with toilets so that they could multi-task on their morning routine.
I have seen the PJ thing. Truly Idiocracy.
This is just part of the liberal dreamworld in which everyone is immature and pleasure-seeking. The professors are ensconced in their “ivory tower” so they can promote such lifestyles. Why mature...maturity is so “uptight” and then. Perpetual preadolescence is the answer.
