I can not agree with with you more. I've shared (and still share) student housing with people training to be secondary school teachers. One of them is genuinely smart and would be a great teacher. However I've meet people who are becoming teachers because they think it will be easy and after a five minute conversion with them have been left with the feeling that they struggle to get dresses in the morning by themselves.
More money to teachers and dissuading lazy people to become teachers is clearly the best option regardless of the subject or area of teaching that they are entering.
Noise proves nothing. Often a hen who has merely laid an egg cackles as if she laid an asteroid. -- Mark Twain
