Well, here goes….
In Wizard of Oz, Dorthy lived with her parents in which she thought she didn’t want to live there anymore! When a huge tornado came through, and it took Dorthy to a far away place hints “where not in kansas anymore todo.” She follows the yellow brick road and meets a few friends along the way…
The wicked witch of the west stands for the railroad industry back in the 1890′s, and the good witch of the east stands for the banks. Which, if you notice in the movie when the house falls on the wicked witch of the west, her shoes are a ruby color, because they don’t use gold anymore, they use silver (I thought that was really cool.)
Dorthy meets the “Scarecrow, ” and he stands for the farmers back in the 1800′s, they were the populist party, and they got out of debt by making more silver coinage. unfortunately, the farmers didn’t understand producing more silver coinage would reduce the value (Dorthy eventually losing her shoes). Then she meets the “Tin Man, ” and he represents the factory workers of the north which the farmers thought were stupid for working in factories for long hours and for so little pay, becoming factory machines themselves and losing their human hearts. Last, but not least, Dorthy meets the “Cowardly lion, ” he represents the Wall street investors because of the poor economic climate of the time. Also, Dorthy’s little dog “todo, ” stood for the teetotaler, or prohibitionists of the time.
When all 4 of them finally get to “the green city, ” which represents Washington, and its delusion of green money, they realizes that they didn’t even need all the stuff they wished for at all, because they had those things all along.
