Why do they have to do this? If these professors and deans did their best to force their students to learn, almost all of them would drop out. They realize this and then ask themselves how they can fix this problem. The most obvious answer they come up with is this: construct a program that will be deemed satisfactory by SJ standards, specifically, a system of 'education' where students are forced to perform, simple, route-tasks that require very little critical thought.
My response to you can be summarized in one sentence. Just because most University authorities are not SJs it does follow that they will not enforce SJ standards, they will enforce SJ standards because the public demands this from them and they need to appease the public in order to stay in business.
