There is something inherently unequal in any teaching situation. The Teacher knows something the student doesn't. It takes a lot of social support for any person to accept that inequality, get around it, and learn what they need and WANT to learn. This is tough for students with culture-bound attitude problems.
A good teacher can play this inequality down and make the acquiring of the unknown a good experience. But it works both ways. The student has to put aside the inequality and attitude to accept what the teacher, good bad or indifferent is offering.
