Read the bio about her. That'll explain just how VERY wrong/misguided your supposition is. Actually, this work and some of her other ones, was writ ten at a time when her husband was a college prof, at a VERY liberal / lefty college. I bet that this comes as a total surprise ( shock ? ) to you. LOL
I read " THE LOTTERY " when I was seven. As is my wont, I then went on ( when I was a wee bit older ) to read ALL of her work. She was a great writter, but a rather troubled soul.
