Are you suggesting that even with immigration the population of school age kids is going to fall? Evidence?
It's also widely accepted that the 40,000 fall in numbers being privately educated THIS YEAR is down to the VAT change couple with the employer NI changes, and not as a result of something that may be happening in a few years time.
And yoyu clearly made some sort of living off that sector, something your younger colleagues are going to be less able to do as a result of the VAT change.

"In 2026, the actual population in state-funded schools

Yes, I worked at a good private school (which, incidentally, has managed to maintain numbers so far). But they, and the whole education sector, are going to have to adjust to fewer pupils. I don't know if you've noticed, but the university sector is in even greater turmoil. Education is not a comfortable place to be at the moment.
As I say, call it the 'politics of envy' if you want to, but the electorate voted for the manifesto that explicitly included the change. No doubt you'd be complaining if they'd done it without it being a manifesto pledge, or if they weren't doing something that they promised.
