Your forgeting that when socialism fails in Cuba as it has in the USSR et al... then the leftist academics will explain it away by teaching that they wern't really practicing "Socialism", "Communism", or "Marxism". It was really a fraudulent attempt by the haves to scam the have-nots into believing that they were working to achieve the people's paradise... If only a "true Communism" could be achieved,or so the academics would tell us, it would work like no other social arrangement. Afterall, they've been discussing it at Berkley for the last 50 years and of course they wouldn't waste time and money on nonsense at Berkley.
