On the one hand we have the ideal: schools will educate children, providing them with the ability to live fulfilled and worthy lives. To be able to contribute to society and understand the world in which they live.
On the other hand we need someone to look after the little wretches while their parents are at work. Preferable as cheaply as possible and without inconveniencing their minders, sorry "teachers".
On the gripping hand (look it up) we have a large number of people who work in schools. They want an easy life. Preferably with as little contact as possible with the kids - certainly not to the point where their academic inadequacies (the teachers: not the kids') get exposed. To achieve this they should be allowed to focus on nice, easy, entertaining topics, rather than ones which are required in real-world situations.
Now consider this initiative: educate / mind / entertain ?
