“The Marxian message of ‘exploitation’ helped sweep communists into power in countries around the world in the twentieth century, at a pace and on a scale seldom seen in history. There is clearly a political market for that message, and communists are just one of the ideological groups to use it successfully for their own purposes, despite how disastrously that turned out to be for millions of other human beings living under communist dictatorships.” – Thomas Sowell
