It's worthwhile recalling that the Wizard of Oz is an allegory about spineless politicians (the lion), heartless industrialists (the tin man) and stupid farmers (the scarecrow). It could be argued that the farmers who sold their land to the industrialists for bargain basement prices in the first (synthetic) recession are no longer, but I think the most important thing is that the Wizard of Oz is a real but frightened entity behind a curtain.
Contrary to the views of mainstream media and their loyal viewers, that smear conspiracy realists while neglecting to report on Wall Street Protests while Yahoo block emails on the subject, there really is an hierarchical group of beings who manipulate our species in pursuit of their own selfish aims. We're a little apathetic when being screwed over, preferring to believe that authority has our best interests at heart. I say we have a virus and the evidence is overwhelming.
