I am not saying native teachers are unnecessary. Most natives work in schools. by the time a kid is school age she has passed the stage of picking up English phonemes from natural native speech anyway. I am suggesting the teachers who work at home, with very young kids are giving the students a great head start. It is fun, not part of a full day of other studies, and in small groups.

these teachers can use audio-visual aids to get the correct pronunciation
