Professors must return to teaching students how to think objectively, not whatto think, echoing the professor's beliefs. That is how America once had the best higher education system
My first encounter with the daunting public school education system was in a little town in the deep south where I applied to be a substitute. To my surprise, the principal of the local high school told me that they could not "take just anybody off the street," one had to have a teaching license to be a substitute, just having a degree would not suffice, it had to be in education.
As I learned much later, most substitutes were generally glorified babysitters who did not really engage the students academically. They just passed worksheets assigned by the absent teacher and tried valiantly to deal with the behavioral problems of unruly students.
