I sincerely doubt it has. I went to a private school which I suspect was much like Ruby’s, and we didn’t really have any classes like that. This is mostly due to the national curriculum, which all schools have to follow, rather than a school specific policy, but I think it’s highly unlikely they had any formal education on any of this. Add to that the fact that private schools are typically incredibly un-diverse in terms of student population, they’ll all have likely spent most of their time around people exactly like them, which makes it very easy to pretend issues like racism and the wealth divide don’t really exist. You’d hope that someone like Ruby, who claims to be a bookworm, would have sought to increase her understanding of the world around her through literature, which is a great way to start to think about some of the real world issues she’ll have been sheltered from, but as we all know she favours children’s books and Victorian romanticisation to the real world.
