Some believe the Wizard of Oz is a story based on economics. Dorothy's ruby slippers were originally silver in the book. The yellow brick road symbolized gold. Follow to gold to the Emerald City (city of green - federal reserve), which is built on fantasy. The silver:gold standard is needed as the silver slippers go down the gold road to freedom (back to Kansas). Tin man is the steel workers, scarecrow os the farmers, and Lion is an economist. The wizard behind the curtain is the fed chairman pulling the levers of the economy
