L. Frank Baum's The Wonderful Wizard of Oz, however, is not only a child's tale but also a sophisticated commentary on the political and economic debates of the Populist Era.1 Previous interpretations have focused on the political and social aspects of the allegory. The most important of these is Littlefield ([1966] 1968), although his interpretation was adumbrated by Nye (1951), Gardner and Nye (1957), Sackett (I960), and Bewley ([1964] 1970). My purpose is to unlock the references in the Wizard of Oz to the monetary debates of the 1890s. When the story is viewed in this light, the real reason the Cowardly Lion fell asleep in the field of poppies, the identity of the Wizard of Oz, the significance of the strange number of hallways and rooms in the Emerald Palace, and the reason the Wicked Witch of the West was so happy to get one of Dorothy's shoes become clear. Thus interpreted, the Wizard of Oz becomes a powerful pedagogic device. Few students of money and banking or economic history will forget the battle between the advocates of free silver and the defenders of the gold standard when it is explained through the Wizard of Oz.
The Wikipedia article is actually pretty good overview: https://en.wikipedia.org/wiki/Political_interpretations_of_T...
I had forgotten about the Wizard of Oz bit! I don't recall if it was meant as an aside or it was meant to support a larger point about public opinion of bimetallism.
The bulk of the middle section of the book is mostly just meh. The final chapter though is something to behold! It's comically bad.
The book remains fairly popular in certain circles. If not for anything else, read it so you can politely refute the person who brings it up at a party.
The Wizard of Oz bit is mostly color, but he relates it to the difficulty state-money theorists have had in coming up with similar narratives, and also that the myth of barter has persisted for lack of a similar anthropological myth for money.
