Countries that people say are Socialist like those in the north of Europe, are really capitalistic societies.
I have known plenty of real socialist countries in the world, and they only share misery. In those socialist countries, like Venezuela or Cuba, the old Soviet World, differences between those in power and those that are not are enormous, bigger than in any capitalist system.
In Venezuela for example, those in power made deals selling the gold of the country, the oil and until recently, had access to favorable exchange of currency that they sold in the black market making a tremendous profit.
In Cuba people earn a maximum by law of something like 30 dollars/month. But people in charge sells access to country resources like permission to place a Hotel or a factory and make millions. All the heroes of revolution living in Mansions in front of the sea while normal people do not have permission to change a broken electrical switch in their houses or feeding the cow in front of their house, starbing.
Cooperatives, like Mondragón in Spain or kibbutz in Israel have their own set of problems. If you pay everybody the same, the best people just get out soon.
