Tragic story with sociopolitical message

"The Yellow Wallpaper" still stands up after more than a hundred years as a terrific story. Coming upon it 100+ pages into the Library of America Fantastic American Tales, it's like we've turned a corner and entered the modern age. Unlike all of the previous "tales" in this collection, it's written in a plain and straightforward colloquial first person. Most strikingly, it's told by a narrator who's obviously intelligent and thoughtful - and not, apparently, deranged. This technique makes the story all the more successful; we buy in to the narrator's voice, she's someone we might know (probably do). Briefly, Charlotte Perkins Gilmore's narrator has leased an "ancestral" summer house. Her husband, a doctor, professes concern about her health - some kind of nervousness or hysteria. We have a whole diagnostic treatise about her condition today, but in 1890s the vocabulary was limited. Over the course of the summer, she becomes increasingly disturbed by the wallpaper in her room, imagining among other things that it has bars, a woman is behind the bars, shaking them, trying to get out. Meanwhile, her husband treats her with the greatest of condescension. The symbolism may be a little heavy-handed, but the story so credible and disturbing that it more than compensates. I've been thinking about the meaning of "fantastic tales." Not sure this really is one - unless "fantastic" means that any of the characters experience fantasies or see visions. The Yellow Wallpaper seems to me a very realistic, tragic story with a strong sociopolitical message.
