From the beginning, humanity and communists did what they need to do for a single reason. Improve your reasons. You can say that he goes to work because he needs to support his family, but that also improves himself. If he lets his family die, he will be very sad, and he will never get better anyway. Marx says that it is embarrassing how humans want power and money. Bourgeoisie seems to be McDonald's in many ways. It was originally a restaurant.
The second part, proletariat and communists explain the role of communists in the role of proletariat. Communists stand on the side of proletariat and share a common goal. "The direct purpose of the Communist Party is the same as that of all other proletarian parties: to form the class of proletariat, to overthrow bourgeoisian dominance, conquer the political power of proletariat." Property, and said: "Bourgeoisie's private property is the ultimate and most complete representation of the production and possession system.The system is based on a class confrontation and is the exploitation of many people." (1) Marx
Then, the "declaration" discussed the relationship between the Communist Party and proletariat. The direct purpose of the Communists is "to classify proletariat, to overthrow bourgeois dominance, and to conquer the political power of proletariat". The Communist theory explains only the ongoing historical movements. This includes cancellation of private property. Marx said the communists were "criticized" because they wanted to abolish the "right" of getting private property through the result of labor. But he pointed out that workers do not get property through labor. Instead, the "property" or capital they produce can make use of them. This property, managed by bourgeoisie, represents society - not individual power. Even changing it to a common asset does not abolish the right as a property but merely changes its social character by eliminating its class property.
Marx said that participation in communists is the greatest benefit of proletariat. He began experimenting in the opposite psychology saying that the communists would not write down their principle specifically for proletariat. On the contrary, it is only a coincidence that the vision of communism is the perfect choice for proletariat. He said that all other social problems before this were a struggle between oppressors and oppressors. The basis of these fights is wealth. Therefore, Communism hopes to eliminate various classes of society. So remove various property levels and classes. Marx said, "In a sense, it is possible to summarize the theory of communism in a sentence: you can abolish private property." I said there would be no reason to fight without private property.
