Somewhat apropos of my previous post is the following anecdote, which I’ve read a number of times and have always forgotten. I’m pasting it here for posterity’s sake. It is from Daniel Little’s review of David Graeber’s Debt: The First 5,000 Years:
There are many startling facts and descriptions that Graeber produces as he tells his story of the development of the ideologies of money, credit, and debt. One of the most interesting to me has to do with The Wonderful Wizard of Oz.
L. Frank Baum’s book The Wonderful Wizard of Oz, which appeared in 1900, is widely recognized to be a parable for the Populist campaign of William Jennings Bryan, who twice ran for president on the Free Silver platform — vowing to replace the gold standard with a bimetallic system that would allow the free creation of silver money alongside gold. … According to the Populist reading, the Wicked Witches of the East and West represent the East and West Coast bankers (promoters of and benefactors from the tight money supply), the Scarecrow represented the farmers (who didn’t have the brains to avoid the debt trap), the Tin Woodsman was the industrial proletariat (who didn’t have the heart to act in solidarity with the farmers), the Cowardly Lion represented the political class (who didn’t have the courage to intervene). … “Oz” is of course the standard abbreviation for “ounce.” (52)
The symbolism of the “yellow brick road” needs no elaboration.
UPDATE: As was been pointed out by Thomas in the comments, this was discussed long ago in the Journal of Political Economy.
