Today is May Day, the first of May and a "workers' holiday" in Communist countries where the workers stand around malnourished and deprived of volition while their leaders salute themselves with military parades. This blog has relevant material -- posts regarding the realities of communism. Of course, for fuller insight into the flaws of communism as a theory, read Richard Pipes' excellent dissertation, Communism: A History. And for an in-depth examination of communism in practice, there's The Black Book of Communism: Crimes, Terror, Repression, edited by Stephane Courtois.
Meanwhile, in the real world, Commies are as Commies do.
