nother common rags-to-riches plot is the marriage plot (see: Cinderella). Typically in this case, a poor straight woman becomes the love object of a rich straight man and thereby gains wealth. Here the world also fails to be changed. This world suggests women should become sexual objects to rich men if they want to become rich. Such, of course, is our world, which also has consequences for purpose, theme, and audience. (It should be noted that in many Cinderella stories, the character arc is fairly shallow: the love object starts off being extremely desirable—that is, beautiful, good, selfless, etc.—and her desirability is simply better showcased by a “change” like a makeover. It is her desirability that actually changes the lover, who goes from, say, an asshole-with-a-heart-of-gold to learning how to be a better person.)
As Kurt Vonnegut says (see the chapter “What Is Craft?”), the Cinderella story makes money. People consume it and reproduce it. This means something. There are all sorts of interesting theoretical reasons for this, and most of them boil down to: the story says that there is hope of becoming powerful in a system by accepting your powerlessness within it.
