"Cinderella, The Legend" fits the Protestant ethic because the moral principle in this fairy tale is that good fortune can be merited. The story shows sibling rivalries and in some way sex-role stereotyping. It is an interesting fable about socialization. In Cinderella, the author conveys the idea that virtue will be rewarded whereas evil will be punished.
