And teachers are magically good?
And they somehow magically teach you everything?
And it's not just about parroting by any means. Little of what I use professionally these days came from school. I've picked up the skills I need from books, and these days supplemented by Google.
Who taught you how to research? Who taught you the skills to be life long learner you are?
Teachers are not always good, nor magical, or do they teach everything. I think you are under the impression that I, and I alone, as a teacher should impart everything a person needs to know on one person. If so, then that thought is delusional. It takes many teachers, using many different methods to do the job properly.
Loren, you have a severely biased opinion based on your limited experience with teachers. Until you are a teacher, or know one intimately, you will have no real idea of what teachers do, or how they do it.
