It would be great for you both to point us to the many posts that supposedly speak about this issue pushing state schools over the edge or the so called 'collapse' of state schools.
Plenty of posters over all these tedious threads have posted stuff basically saying to state school parents 'see look what you're making me do, here's how it will affect your kids', see this from above
Maybe the state school parents should give a Damn if the private parents cease to be able to pay. I’m sure that the area where all the privates are concentrated would kill for a massive influx of ADHD and ASD kids into the classrooms.
Maybe the state school parents will also care if the local private shut its doors and therefore removes the access to its pool/facilities for the neighbouring state schools.
Maybe the state parents who can’t afford the house near to the school should care that the private parents can easily outbid them for those houses and all the surrounding ones. And will.
Maybe the state school parents should wonder whether the total tax take will drop when the mothers (let’s be honest it won’t be the dads) go part time because they don’t have to pay fees now but do need to be able to cart the kids around to their extracurriculars (which used to be available for the state school kids but private parents clearly have sharp elbows).
It is a big deal to move from private to state. The two are very different beasts. But people will do what they have to, and will make sure it’s not their kid who suffers.
I don't believe state schools will collapse, they'll just carry on as before. As a few people have said, in a lot of areas there are places in schools. I don't know who the post that I've quoted above is actually aimed at, but the people who it will scare are those with ASD/ADHD kids currently at private school. Some state schools are actually brilliant at educating those kids, but there are no guarantees that the ex private school kids will get into those schools. Their parents might not even know to apply for them because guess what, they may not be rated Outstanding. And the schools that aren't brilliant at it, well the parents of the ASD/ADHD kids are already used to getting fuck all help.
