So many children's fairy tales were actually satirical commentaries of the governments, the royalties, and the evils of the ruling class placed on the people in Europe
I am of the belief that the "Wizard of OZ" story was just such a contemporaneous parody about the U.S. gubmit, big banks of the east and the rights of the common man. So actually, the image of the good witch telling Dorothy of the "powerful magic" she had at her feet was exactly about those citizen rights.
Thus making this meme closer to the truth than may seem obvious at first glance.
