“Who are the oppressors? The few: the King, the capitalist, and a handful of other overseers and superintendents. Who are the oppressed? The many: the nations of the earth; the valuable personages; the workers; they that make the bread that the soft-handed and idle eat.”
Do you think that he would side with today’s unions aligned with organized crime?
