> Who needs teachers, then, if they are so ineffectual? Might as well replace them with a canned video course.
Replacing teachers by canned video courses does not a priori sound like a bad idea.
The central reason why this is not done is that school also serves as daycare, so you need some employees to supervise the children, i.e. removing the teachers will hardly decrease the employee count. All together, if we consider the additinal cost of creating the video courses, this measure would hardly decrease the cost of schooling. So politicians think "never change a running system" and "avoid the trouble with the teacher's unions" and leave everything as it is.
