This is a public forum, and there are some people who are angry and vintictive on both sides.
I don't condone the pp saying not to do any fundraising, nor the couple of posters on another thread who suggested applying for state school places they don't need.
It's no better on the other side: I've seen posters saying that they can't wait for private school kids to be pulled out and they hope they'll get given sink schools and be bullied for being poshos.
I believe (still the optimist) that these views are in the minority on both sides, and that the individuals are angry. As a minority, they are also powerless. None of these vindictive suggestions(on either side) are actually going to happen.
I believe the people making actual decisions will be more measured.
... That schools will still support the community as far as they are able to, even though their funds will be more limited as they provide hardship funds to existing parents and try to keep fees down.
... That the Labour Party doesn't actually want to harm private school kids, even though they're willing for a cohort who already suffered covid to be sacrificed.
But despite that, there will be real consequences to this policy. That's not threats, that's not vindictiveness, it's just prediction. It's a substantial new tax on an area which currently provides huge social good, and targeting a demographic who are already under financial pressure (as everyone is) but have significant options available to them.
Every policy has negative consequences.
Pretending they don't exist - not thinking through whether the cost is worth it for what you'll gain - is poor government.
