The facilities would be shared between all of the pupils, so every one of those 7 classes would have access to the private schools gigantic playing fields, full range of sports equipment, up-to-date computing equipment, music facilities - many have art studios with kilns, proper theatre spaces, recording studios, large libraries, SEN departments etc. Some of those things could be moved around to the other schools, or pupils could travel to the private school (using their minibuses/coaches) to use them regularly.
The facilities are there because the parents are paying fees. Once they stop all the facilities will go, unless the state pays for them, so where is the money going to come from?
Parents currently paying school fees would no longer have to, yet their children would still have full access to all of those facilities (just have to share them a bit more).
What facilities? You need money to maintain those and pay the staff. No money, no facilities, no staff.
Parents previously paying school fees would suddenly be aware of things like the narrow nature of the national curriculum, would make a fuss to ensure that languages, arts, public speaking, lateral thinking and subjects like psychology or philosophy A-levels are still available to what will now be the whole of the nation.
This is very undulating to parents whose children are in state schools and who are aware of the failings of the system and who are trying to do something about it. Why do you think that people who have previously paid fees will be successful? You are being patronising and insulting to all the patterns who currently have children in state schools.
Statistically, children with the potential to cure cancers are more likely to come from that 93% previously underfunded than a narrow 7%, so it's more likely that society will benefit. Some future genius in science or technology, or a great musician or even politician will no longer be hampered by having to share a textbook between 3, with not enough equipment or supervision to do more than the absolute necessary to pass an exam.
What's stopping the state from investing in the state schools? Also, as above, no fees, no textbooks. They won't magically appear.
It is monstrous that children are not all given equal access to equipment, resources, teachers' attention etc. Can you imagine going to a playgroup where some toddlers were given only a few chipped bricks and a couple of toys to be shared between a large group of them, while the others were fenced off into a large space with tables filled with jigsaws, clay, brand new bricks, were surrounded by staff to sing songs and learn the alphabet?
It would feel wrong.
What's stopping the state school staff from singing songs with the children and teaching them the alphabet?
How is taking from one group going to make the other group better? Wouldn't it better if the state invested in the state system instead to strangling the private one?
It's so easy and temping to see it in black and white, but that's short sighted and it won't solve anything long term. Investing in the state sector so it's better than the private one is a much better solution.
