The dangers of compulsory education

‘Attendance is now compulsory for every young witch and wizard,’ he replied.   ‘That was announced yesterday.  It’s a change because it was never obligatory before.  Of course, nearly every witch and wizard in Britain has been educated at Hogwarts, but their parents had the right teach them at home or send them abroad if they preferred.  This way, Voldemort will have the whole wizarding population under his eye from a young age.’

Damn, that Voldemort is eeeeevil.
