Socialism cannot exist without there first being a system that recognises some form of private property, whether that be a monarchist system or a constitutional democracy. Once in power, socialists will then set about redistributing that property away from the owners, giving it to others. It is a philosophy with a foundation built upon theft, for there must be something to redistribute in the first place for a socialist system to operate. It's like a virus, it needs a host for it can't exist on its own merits. The modern Scandinavian countries are living examples of how socialism rises and feeds on the wealth created by capitalism. Edit to add: unlike capitalism, socialism is not a creative philosophy.
