I would say the Soviet Union and the Dutch VOC were both bad for the same core reason: they were an ideological extreme. Capitalism is only a good system, if it is localized and regulated. Otherwise a small group of people will come out on top and exploit everyone else. But the same holds for communism, as clearly seen in any nation attempting communism, you inevitably get a dictator who will exploit the people for his or her own good. The difference is that when you weaken communism by implementing only parts of it, like universal healthcare, or unemployment benefits, then we call it socialism.
