The other side of that is that there are also a lot of (generously) mediocre teachers who have simply continued to stay and “teach” regardless of how many years ago they mentally checked out. They’re toxic, and sour, and that comes through in their lessons, which definitely impacts students who actually want to learn, and who are relying on their teachers to provide the foundational education that’s expected to ensure they have a path to prosperity. Which seems like a steadily dismantled pipedream, for kids who have any awareness of the current state of the world.
