Imagine if you had spent 6 hours a day 5 days a week for 12 years being forced to play sports. If the idea provokes violent horror in you you now have some idea how the people you would be forcing to stay in school would feel about it. And make no mistake; compulsory attendance at allegedly educational institutions is forced. Whether the superior outcomes for those thus compelled outweighs the poorer outcomes and massively less pleasant experience of those forced to share classrooms and teacher attention with sullen youth there under pain of imprisonment is aquestion to be dealt with in ones own head.
