it's not everyone that are previledged to go to private schools. Some of us didn't even have nearby private schools in our surrounding so we had to make use of the one we had and to the best of there ability, they've managed to train amd nurture us without we getting exposed to vices like porn or faulty vices like these you're mentioning here. Private institution might have better staff and teaching aids but in today's world, those are not just what's responsible for sound students but in character and mind. A lot of the students that easily gets spoilt are those whose parents have failed woefully in terms of bringing them up in a good way and the society gives the blame game to the schooling system they went to forgetting that it's just that the school is building on an already existing foundation that's put in place by the parent.

It's not just about public schools. As long as the leadership of the school has good moral and administrative prowess, you could get a better moral in public school than some public schools that are just known by thier good name.
