Similarly, it can be beneficial to one's someone's career to get a high score on TOEIC, so adult classes prioritise teaching people to get high scores on TOEIC. The "education" system is extremely well aligned with the economic incentives.
That is exactly what I meant by Galapagos syndrome. I should have written external(= business conducted in English) economic incentive.
The elephant in the room is that 6/12 years school here are focused on rote remembering for the next entrance exam rather than learning.
