Marx wrote to Engels: “In my opinion, the greatest things that are happening in the world today are on the one hand the slave movement in America begun by the death of John Brown , and on the other the serf movement in Russia... I saw... that there was a new slave uprising in Missouri, naturally repressed. But now the signal has been given. If things get serious… what will become of Manchester?” This is Marx's idea of ​​why a proletarian revolution will begin. Marx built his vision of communism based on the human and technological potentials already established in his time, so that socialist then became a new society. The new successful working class would then initiate plans that help address all the problems created by the past society and the revolution would unleash a social dynamic. He wanted to get rid of all the patterns and tendencies present in capitalist societies. His theory was characterized by the absence of money, social classes, and political or economic ideology. For example, in China communism is used as wealth redistribution where the rich take all the money and redistribute it to the poor. In Marx's eyes, communism was the only way for people to be treated equally and for there to be an end to the division of social rights.
