My wife taught classes at the college level. Told me stories. I suspect that many parents weren't even aware that their kid wasn't even coming to class half the time. Then they would question their appropriate grade. Much of the class was physical so you had to be there. She felt sorry for many of her students. Pretty helpless generation. Either they weren't paying attention, or the parents had no contributions. I suspect both. Hell, I knew someone my age that never did laundry until his fifties.
