One of the kids in my son's school has two Indonesian parents and can only speak English. It is an English-language tuition school but not one of the very expensive ones, so they are not super rich. For some unknown reason they think it is better for him if he only speaks English. I remember his teacher telling me it was cruel. But it is getting much more common now - when kids get taught in English, speak English at home, watch English media like youtube, speak to their school friends in English, where would they actually ever get the chance to speak or learn Indonesian?
