The numbers of teachers can hardly be an issue but the quality might? If the numbers of teachers is anything to "go by", they're not doing a very good job at the moment because the standard of literacy isn't good and spelling is atrocious.

Old hands will know I've said this before but when "they" tried to mass-produce teachers (= give them a short-cut in to the job) it introduced a militant bunch of people who've now mass-produced more of similar ilk.

Those "new" people looked at older teachers who had, during their life as teachers accumulated a nice house, nice family life and nice cars. Those "new" people took no account that the older teachers had carefully earned their position, the newcomers wanted the same and they wanted it NOW. After all, they were teachers just the same as the older ones?

When you looked at the "type" of people going to the new-fangled "teacher training colleges" you saw a dirty, scruffy, lazy, indisciplined, casual bunch of people who had no regard for punctuality, they were going to teach the kids to be just like them with the same attitude to the "old school" and they did!
