I've been speaking with other more informed communists and they've told me that none actually exist. Is this true?

China, Laos, and Vietnam: now notoriously capitalists. Workers work 12+ hours with no protection in horrible factory conditions. Suicide rates are so high that suicide nets are installed. The air is so polluted millions die from lung cancer, especially factory workers w/out basic masks. Corporations dominate

North Korea: Undemocratically ruled by the Kim dynasty. Jong un indulges lavishly at the expense of his citizens, ordering millions in fine wine and trips from Denis Rodman. They might be the most socialist though, as Juche seems to otherwise be democratic.

Cuba: Sanctions have taken a massive toll, but even taking that into account the country still has its own problems. They have massive food shortages and inventory probs and aren't self sufficient after 60+ years. Why couldn't they've use machinery imported from the Soviet Union to develop their agriculture and fishery? The Soviets supported them heavily. They seem to be incredibly mismanaged or corrupt

To be more specific, I'm looking for unbiased biographies of Mao, Lenin, and Stalin. By "unbiased", I mean not clearly riddled in western propaganda or authors who are apologists. Also, it would help if you can tell me where I can download them as ebooks.

The only thing I found for Mao was Mao: The Unknown Story by Chang, and the Private life of Chairman Mao by Zhisui. Both are full of blatant hatred and Western propaganda of Mao, so they are full of shit. I can't find anything else in english though, there's a chinese one but it's sponsored by the CPC and is too long, so again it isn't reliable. For Stalin, It's like everything about that man is Western Propaganda, I can't find any unbiased source. I know Stalin isn't some saint and killed lots of people, but it's like Westerners believe that's all he did even in his free time! I saw one book say he killed 1 million soviet citizens per year, wtf! There is zero acknowledgments at all to the successes from his rule. The closest I found was from a former Soviet Historian using released Soviet Archives. Apparently he did one on Lenin too, and seems unbiased enough. For Lenin it's the same problems w/ propaganda. Albeit, I can rely on his own texts as well to get a view on him.
