Not on fees, no - on school development funds. If your school doesn't regularly raise the odd few million to build a new pool, science block, sixth form study area, art centre, sports centre... then it's very different from the ones I'm familiar with.
And would those be the bursaries used to ensure the school in question sits comfortably high up on the league tables, and has a good record of Oxbridge entrance? Because no school can afford to stop those - they're central to marketing to new parents, and would be especially so if the tax breaks were abolished and schools would be fighting for every student.
Private schools are businesses. They tout for new pupils at international education trade shows, they take a zero tolerance approach to bad publicity, and they are incredibly keen to achieve a high UCAS score and Oxbridge entry rate. They won't jeopardise that, they'll just shuffle the cost onto existing parents.
"I was careful to say taht I did not regard everyone in receipt of state benefits as spongers. Only those that are able to work and don't. There is quite a difference."
Hmmm. And what makes you think there are legions of such people? And actually, what makes them relevant in any way to this conversation, anyway? It makes no sense. It's a non sequiteur.
