Apparently, the Wizard of Oz is not about Wizards at all, its about banking, at the highest Babylon the Great levels.
For instance, in the book, the Ruby slippers are silver, which represents the metal that was used as real money before the bankers sold us worthless paper.
The yellow brick road represents Gold and the gold standard.
The Emerald city represents the greenback.
The tin man represents industry.
The straw man farming.
And the Wizard is really just a harmless little man who decieves us with his tricks, just as we could crush the ruling bankers if we pulled back the curtain and see their frudulant act for what it really is.
If you Google it you can probably find a much more indepth analisis of this Great Depression story, and just as we are getting deeper into another manufactured depression, so you can still watch it, (providing its ok to watch films about Babylon the Great, Rev 18 = the fall of Jewish banking, not a lack of Christmas card sales!).
