I was surprise that the majority of the World is run by Socialist Government.
Actually, there is a misunderstanding about the list referred to. There is a note at the beginning of the article "This article is about self-proclaimed socialist states."
The same would be misleading about self-proclaimed democratic states like "Democratic Republik of Korea" and "German Democratic Republic".
There are many dictorship that call themselves "democratic" or "socialist" because it sounds good. Do not look at lables but at actions.
