Alrigjts, let's. Firstly,Marx very well knew the downfall of communism. He wrote it in his book that communism will only succeed in a utopia of world, where greedy men don't exist
But one thing i have always like, been fascinated about is, how patriotic russian scientists were Like, USA was rich enough to attract the greatest minds all over the world to it, yet ussr managed to stay quite close in technological advancements
Unfortunately, greedy and men can't exist without each other according to the cooler Karl (the Holy Roman Emperor)
Even though he knows it'll destroy individuality, Karl believes assimilating all existence with his own will finally bring peace and salvation to all.
