I don't think the point of universities and degrees these days is to learn anything. It's just something you have to do in order to get a good job. That was certainly my experience. I went to a so-called top university, and I didn't feel like I learnt anything remotely relevant to what I do today. All I got at the end of it was some letters after my name.
According to one model, students have three primary motivations: 1) passing the classes and getting the degree; 2) getting good grades and otherwise being good on whatever is being measured; and 3) learning things. Teaching is most rewarding when the third motivation dominates, but the other two are often the necessary evil that pays the bills.
