It's seems notable that all three of those examples are sports related. At least in American society (the only one I'm familiar enough to speak about), I think that sports culture is a way better example of breeding egoism and "us versus them" orthodoxy than academia. I agree that the dynamic isn't exclusive to Big Ten universities, but I think it's reasonable to argue that the esteem placed on sports in the Big Ten (and other high-performing D1 universities) is what enabled these abuses to happen. Any time an institution is revered enough, whether it's a sports team or a religion or something else entirely, there's a chance that someone involved will take advantage of the status to try to get away with something due to the lower amount of scrutiny.
