The Secret of Oz (2009)

Could it be that solutions to the world's economic problems have been embedded in the most beloved children's story of all time, "The Wonderful Wizard of Oz"? The yellow brick road (the gold standard), the emerald city of Oz (greenback money), even Dorothy's silver slippers (changed to ruby slippers for the movie version) were powerful symbols of author L. Frank Baum's belief that the people—not the big banks—should control the quantity of a nation's money.
