I don't blame the foreign teachers. It's the parents and the school runners who exaggerated too much on the effectiveness of hiring "Native language speakers" and the ignorance of most of the parents who never learn a foreign language before and wanted their children to keep up with the trend. I still feel indebted to our domesticated language teachers. Without their teaching, I wouldn't have the good foundation in grammar. Since the schools needs "natives", they even hire illiterates, under-qualified and non-certified ones to fill up their needs. Some even ask for young, good-looking whites and females! I think the Koreans are right to the standing up for corrections. No sooner, I wish the Chinese should be smart enough to follow up to do the cleansing.
