Dorothy, a sort of proverbial ‘Everywoman’, lands on the Wicked Witch of the East (the East-coast bankers), killing her, so freeing the Munchkins, the down-trodden poor, but the Wicked Witch of the West (the West-coast bankers) remains loose.
To deal with her and to get back to Kansas (normality), the Good Witch of the North, representing the electorate of the North (this is less than 40 years after the civil war), tells Dorothy to seek out the Wizard of Oz (‘oz’ being short for ounce, the means of weighing both gold and silver). She also gives her a pair of silver slippers (as they were in the book – they became ruby ones in the film). Only these silver slippers will enable her to remain safe on the yellow-brick road, representing the bankers’ gold standard, as she heads towards the Emerald City, representing Washington DC.
On her journey, Dorothy encounters a Scarecrow, representing the farmers, who do not have the wit to understand how they can end up losing their farms to the banks, even though they work hard to grow the food to feed a hungry nation. If only they could think it through!
Next, she encounters a Tin Woodsman, representing the industrial workers, rusted as solid as the factories of the 1890s depression, and who have lost the sense of compassion and co-operation to work together to help each other during hard times. Also, a spell cast upon him by the Wicked Witch of the East meant that every time he swung his axe, he chopped off a bit of himself – he downsized!
Then the growing party encounters a Cowardly Lion, representing the politicians. These have the power, through the power of Congress and the Constitution, to confront the Wicked Witches, representing the banks, but they lack the courage to do so.
Dorothy is able to motivate these three potent forces and leads them all towards the Emerald City, whence ‘greenbacks’ had once come, and an encounter with the omnipotent and wonderful Wizard of Oz.
