The Pevensies were very privileged.

This makes sense, because Lucy was a stand-in for Lewis’ goddaughter. It wouldn’t have made sense for her to be working class.

The Pevensies were from Finchley, a wealthy area of London at the time.

Unlike working class children who had to stay with any random family, these kids got to stay in a mansion owned by an uncle.

Peter and Susan go to boarding school in later books.

Even the way they speak - that’s how posh kids speak.

Yeah obviously, just the act of getting out of London doesn’t mean they’re poshos. Everything else about them indicates that though.
