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
