The subject of the March 13 editorial should have been given attention much more before. The so-called obsession with native speakers/teachers in every corner is improper emphasis. These native teachers come in large variety from England, Australia, United States (covering wide areas with vastly different dialects) and hardly can fill in as the "Queen's English." There is "Singlish" from Singapore, also.
I suggest put more stress on India, whose English-speaking quality remains unbeaten, as India is unbeaten in the IT field. This is solely due to its expertise in proper English, and insistence on heritage with British colonization for nearly 200 years. The Indian alphabet also has an indirect effect in correct pronunciation, as also in English grammar and composition.
May I suggest that the Japanese better look to Indian English teachers rather than the so-called native teachers who under the JET Program are having their big share of the Japanese market. Let us open our eyes and ears and smell the proper channels.
