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). The yellow brick road, silver slippers, emerald city, and hapless Wizard presumably speak for themselves.
