Well, except that most college professors don’t harass—so that isn’t the natural effect of a hierarchical system… Now, whether a hierarchical system makes it harder to deal with the bad actors, that’s an interesting question (and the topic of a recent Chronicle of Higher Education piece, which has resulted in a lot of discussion with IMO good points on all sides), but an unsettled enough question that I don’t think you can say it’s a “natural” result, either.
