I did sit in a couple of classes over the last decades and let me tell you my experience is that it is the teachers who are not woke or based who get more flak than before. If you are chauvinistic kids today will call you out for it and will often not accept your appeal to authority. That is good actually. My viewpoint is that from an inner city school.

Kids are communicating much more in the classroom and in a way that teachers can't control, this means that teachers are also out of the loop which some really dislike.

That said the amount of work teachers do increased and the controls they experience, too. But so did the hours that the students have to work. I do have to agree with that kids aren't giving older teachers as much credit as a couple decades ago. This might be related to less respect for old people, or that the teachers are less at it and/or a bit out of the loop. If you are older the noise does affect you more.
