@twistyizzy , I am so sorry.
I don’t believe that the supporters ever will admit to the issues around the policy. It was not analysed properly, introduced at a time to squeeze out every last penny of desperate parents and it fits into an overall us vs them agenda.
It is ugly but people fell for it. Some genuinely believe that private schools are a luxury for SEND parents - and that private education is unpleasant and should be taxed heavily (many wishing that private schools disappeared overall).
admitting this would force them to (at least to themselves) admit to either being easily fooled or to being spiteful. They want to continue to believe that they are good people on the right side of history.
Unfortunately the money for state schools will never materialise, and labour’s plans for state schools are very worrying (curriculum, access, etc). I am increasingly believing that the best thing to do is to focus everything on our own children whichever schools they are in. The social contract is broken.
