The role of teachers is to keep kids out of the way so that grown-ups can do stuff untrammelled by brats. Naturally, this philosophy applies just to state schools, not public schools. The latter are there to provide the next generation's ruling class. Ask any Tory politician.

We have a terrible shortage of doctors, nurses and care workers, driven by ten years of Toryism. If any of those workers had to stay home to look after children, the NHS would collapse. There is no wriggle room, either in terms of staff, A&E or hospital beds, for a crisis. And there should be. But Tories don't think that way. They can pay the state-educated doctors to let them jump the queue, so why would they?
