We could get the kids to plant turnips in all the school playing fields, get them to harvest them and then the canteen can cook them up for school dinners. And there you go, free school meals for everyone. Just a bit of effort on the kids part.
And, as they still need educating, they can do it after school hours. Thereby solving the problem of what to do with the little darlings while mum and dad do their 80 hour weeks. Genius!
