Donna isn’t happy with her life. She thinks she is working too hard for too little money. (Who isn’t!) And she thinks her life will be better if she could find a wealthy man. There are some interesting economic ideas in this song. One is the idea of the marriage market – as someone who is wealthier, all else equal, will be a more-appealing potential partner.
This song could also lead into a discussion of the marginal utility of wealth. What would an extra $1,000 mean to Donna? To the “rich man” on the yacht?
