Socialism worked for Mao. It worked for Fidel Castro. It worked for Erich Honecker and Nicolae Ceaușescu, until the very end. It worked for Adolf Hitler and Benito Mussolini, again with sad ends that didn’t inflict anywhere near enough pain to negate the years of glory and power that went before. It worked for Hugo Chavez, who like Castro, parlayed socialism into a multi-billion dollar fortune, and it has worked so far for Nicolas Maduro. All of these psychopaths, and many others, got exactly what they wanted out of socialism. From their point of view, it is a successful ideology.
