I respect your reasons for being driven to do the best for your kids.
I remember going to a certain posh school for girls nr Jockey road, Sutton to help deliver cement and sand, for some building work when I was about 10 (no one batted an eye lid back then at casual wagging and illegal child labour)
The teachers looked at me like I was some kind of navvy. I looked at the school and the kids in the play ground, like they were from Mars. I think if they had tasers in those days I would have got tasered.
So much has changed. So much hasn't!
Lol - how long ago was that? I may have been in the playground, although if I looked at you it would have been with longing to join you and a wish to escape!!!
