Disallowing Learning

In the latter stages of my teaching career, I noticed the greater and greater tendency to disallow the teacher-learner dynamic on the grounds that the superiority implied meant that it was a kind of “punching-down” oppression. It became more and more fashionable to make a public exhibition of one’s humility in learning, Rousseau-style, from the children. Of course everyone learns stuff in whatever profession they are in so teachers would always be learning things (and sometimes from interactions with children) but this doesn’t justify disallowing the process of teaching. I wonder if there is also now a tendency to disallow the idea that there is a reservoir of wisdom in age in spite of the fact that a definition of wisdom might be the accumulation of knowledge from time and experience?
