As far as I'm aware, International students don't pay more for fees in British private schools compared to British citizens? I've been on a couple of the websites and it doesn't seem to mention any of that at all?
I specifically only mentioned day schools with regards to fees because I'm sure even you would agree that £40k fees are not within the grasp of most working UK parents, regardless of how much they try to cut back. However, fine, let's take literally the most expensive school in the UK . Seemingly this is concorde college, at £18,000 per term for full boarding.
9 students paying 4k a term. 1 student paying 18k a term (even though again this is a boarding pupil but whatever, let's run with it). This gives a median of £4k per term or a mean of.....£5.4k per term.
This is still not hitting the £7k per term for day school fees, let alone the £12k per term average of boarding.
Families who are sending 3 kids to a 4k/term private school, even with a 25% 3rd child discount, are paying £21,000 per year on their kids education alone. And this is at a school that doesn't come near the average day school fees. Your take home pay in a median household income in the UK, from a gross of £45k (which
@Buster15 tells me is actually higher than it really is), is around £36k. Assuming you're contributing nothing to your pension. If you genuinely think a lot of the parents are not well off, you either have a very distorted view of what well off means, or those people are not being completely upfront with you about their finances.
I'm not sure we do agree because a class war would be something to affect the upper classes, which this policy does not (as they can continue to pay the school fees comfortably regardless).
So again, nobody is saying all the parents are flying around on helicopters. But the average parent sending their kid to private school is not exactly just getting by, regardless of how much they scrimp.
Edit: Just wanted to clarify by the way that I am really not trying to attack you or your decision to send your kids to private school at all. I know this may be how its coming across, especially online but that isn't my intention. I'm just challenging some of the figures you've put out.
