I feel similarly. I never cared about that time period because I figured everything was probably just racist and sexist and there's no fun technology. But lately I've been reading and learning more background just for fic. I think for a modern person encountering the Jeeves world, it can seem kind of exotic because everything is so rigid and restricted and prescribed. I now find myself curious to get to the bottom of what people were really like, underneath all the rules and the propriety. And I'm interested to learn more about the consequences, about what living like that does to a person/to a society.
