To be able to migrate to other countries and be able to find a better paying job requires knowing more than one language. Knowing English is even better especially when a person wants to go to England, Australia or America to have higher education or explore new options for a better job or a career. Proficiency in English becomes an essential requirement. One's culture is not going to help to survive in a foreign land. Besides manners, work ethics and life style issues the language should also be seen as an essential survival tool.
Well, in Thailand English teaching and learning problems cannot be solved by employing the "native speakers". As mentioned earlier, Switzerland, and many other European countries where teaching and learning English is a big success, do not rely on what my colleague Dr. Sorin, call as "na (t) ive" speakers but on their own teachers of English.
In Asia, a good example is India. Although colonized formore than two centuries India does not employ foreigners to teach English. Yet, it has a huge population that can speak and write English. It has grown its own crop of English teachers. They are all graduates of Indianuniversities majoring in English. Singapore and Malaysiaalso followed the same model. It created its own pool ofexcellent English teachers.
