I have no idea what you are talking about. Do you have any idea?

I never said why natives, or non-natives, are hired here in the Arab world. Perhaps you are right, it is cheaper to hire non-native speakers of English.

My point is entirely different. I am only saying ideally one should be hiring a teacher who is really competent, regardless of whether they are natives or non-natives.

You are right. Relatively few people who are non-natives achieve the mastery of the language to the point that they are able to outplay natives at their own tongue.
