In one sense we can see that Red is dead: For decades the holiday of the socialist-labor movement, May Day, was celebrated widely. It’s not anymore. And yet, leftists still often reference the guru of the socialist-labor movement, Karl Marx . . . even though the essence of his worldview, his progressive-developmentalist theory of history, should by now be recognized as deluded. Leftists still reference Karl Marx as the oracle of post-capitalism.
