L. Frank Baum did not write children's books!
He was trying to warn the American public of the whole sordid plan that the banksters had prepared for us.
His works anticipated such century-later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones(Tik-Tok of Oz), women in high-risk and action-heavy occupations (Mary Louise in the Country), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).
Did we pay attention?
The little people (that's us according to Mr. Rockefeller) cowered in fear in the Emerald city ruled by the mighty greenback which they required to feed and clothe themselves.
They lived in constant fear of the evil witches with green skin (occult masters of the world) who would swoop down on them.
And swoop, they did, even back in the late 19th century. Because the masters of the world had flying machines, airships that they used to secretly travel overhead at night, when the poor little sheepies were tucked in their beds, or drunk on whiskey sold to them by the masters for precious greenbacks.
Will you all make the same mistake again?
Because if you acquiesce to the masters this time, well…. they've already decided that there are 7.4 billion too many of you. So you won't survive to collect your pensions anyway.
Evil cackling laughter
