There is a major logical gap in your argument. The fact that some or many non native speakers make mistakes doesn't imply that all non native speakers of English make them as well. The fact that you haven't -say- found them, doesn't equate with proper or believable statistics either. After spending 30% of my life in the USA, after getting an education in English, I am fully confident I don't make any more or any more significant mistakes than an educated native speaker. Furthermore, the linguistic notion of competence is not defined by the ratio of the number of mistakes to the length of the discourse but, instead, by the ability to express complex ideas and the command of syntactical structures or even how adept one is at devising text coherence. I have quite often found that many of the teachers from the USA or Britain here in China do have an inferior vocabulary in their own and only language. No, there is no reason why they should systematically prefer native over non native speakers. However, if the human resource manager has not the ability to tell a good speaker from a poor one, he will end up making a choice of prerequisites that simplify his job. That's all. It is also an excuse to bring a white face to the school as it commands a tuition premium. It's a commercial barrier. You also made a few mistakes in your brief and not very bright post.
