I hate the impact it has on the rest of society, particularly their state peers.
After COVID DD went sailing for a week, she was the only state school kid on the boat and the keenest sailor by a long way.
The private school kids were there as just an extension of paying others to look after your kids. She learnt a lot, including textiles is strong multiple private schools because the teacher does your work! But ultimately she felt all of these kids would have been in the damaged, hard time group at her local comprehensive.
She went back a couple of years later, this time one other self funded state school kid. A bit older, the kids all did want to sail to a point.
One boarder from Charterhouse, stood out with his only lives 20 minutes away but its great for sport and mates. He was a nice lad, pulled his weight and had excellent manners but was assessed as not boyfriend material!
DD and the other state kid ended up doing all the cooking. There just wasn't time or staff to teach beginners to organise a meal, chop an onion.
DD felt all of the private kids were a bit hollow, a bit unattached, a bit sad. Waiting to pick them up was the weirdest bunch of unemotional adults. Nothing like the excited, sometimes reserved but always warm hugs, at the state school when the kids turn up back from a language trip.
I wish the sailing people would do state school only trips. It's certainly made DD question the bluster and outward confidence of private school kids.
