Ok great post! Not going to lie, at first I wanted to say that the reason the author had the maids speaking like that was to evolve the characters. However, after reading your post, I realized I see more of your points. It would have made more sense if the other characters also had more of a slang bc that is just how people speak in general. In a way, it did reinforce the typical stereotypes, regardless of time. I didn't even realize the comparison of skin colors! I must have either overlooked it or it didn't register. I did enjoy the book overall though as well!
