I have been only vaguely following this, I as an ex-teacher I have seen the view from both sides, but I think the problem is that both views are right. There are amazing committed teachers who work hard and stay in. There are amazing teachers who quit in frustration. Burnout rates can be very high. There are teachers who, quite frankly, I wouldn't inflict on any child.

And that's why I opted out, both as a teacher and a parent.
