Money system is a derivation of land, upon which constructed capitalism. In the first part of the manifesto, Bourgeois and Proletarians, Karl Marx talks about the “oppressor and oppressed” relationship between the two classes. Capitalization of property and lands has changed the social classes from clear division of clergies, aristocracy and peasants into solely two classes, one with capital and the other without. The money system accompanying capitalism set up the ground for “egotistical calculation,” which “has transformed personal worth into mere exchange value.” Money derives from the land but it is not the land; instead, it is an alienation of land. Capital, or private property, can be understood as the transformation and alienation of land, which people work hard for. Because money only has the exchange value but not productive value, proletarians can only earn what is enough for their subsistence. As industry thrives, competition arises between capitalists, for gaining more customer and profit means more private property for the bourgeois. Wages decline as a result of competition, proletarians live a worse life while bourgeois live a better life. When the situation comes to a point, when the majority of the society, proletarians, are so poor that they cannot afford to buy the commodities they produce, the epic of over-production will happen, according to Marx. The suffering of poor and hard life, the fact that working hard doe not pay back proportionally, eventually brings proletarians everywhere together to fight against  the bourgeois. Revolution is inevitable.
