In the past I wondered why the wt did not promoted or operated prvate jw schools to keep children (their source of membership) out of the "world".
Also it was/is frustrating for some parents no being able to send their children to private schools, their are mostly operated by religious organizations in many places. I was pulled out of private schools after failed attempts to get exemption from attending the religious services at the school. I remember going to the bath room or somewhere else and statying there until the "service" was over, scared to death...
