I think this is a problem with the students as well.
Kindergarteners need to be taught by people who are trained for teaching. Eleven-year-olds need to be taught by people who are trained for teaching. But by the time you get to the the university level, you're supposed to be clever enough that you can pick up a subject just by having one of the world's super-experts in the field stand up and ramble in front of you for a while. If you can't learn without hand-holding, you don't belong at university.
