They charge their customers (not "students") horrendous fees and pay their deechers or teachers only peanuts and pocket most of the cash themselves.

Exactly right. The british guy I knew, who is know very firmly an "ex-friend", had his wife write in their advert that our priority is pleasing our students parents.

These places are just a cash cow, and nothing more. The students are the last thing on the minds of the DOS'es and the management.
