In a 1964 article,[5] educator and historian Henry Littlefield outlined an allegory in the book of the late 19th-century debate regarding monetary policy. According to this view, for instance, the Yellow Brick Road represents the gold standard, and the silver slippers (ruby in the 1939 film version) represent the Silverite sixteen to one silver ratio (dancing down the road).
