I suspect the bad humanities teacher is a result of university politics in the "office politics" sense allowed to degrade and stagnate.

Essentially if it takes those who are good at the bullshitting game to advance and compete for tenure bullshit becomes the defacto qualifier.

Making matters better yet worse for "optimizing" in both senses are those who actuly are sincerely interested in thd subject - I have had decent ones who would give good marks and respect those who differed philosophically but could give sincere and articulated explanations and justifications.
