Marxism is based on the political, economic and social theories of Karl Marx. His belief that social class struggle has had a major impact in history and that society should evolve towards a classless system. Marx believed that people are free and creative beings who have the potential to transform the world. He criticized the free market as unregulated. Marx argued that the market economy is coordinated by spontaneous purchases dictated by supply and demand. This has blocked society's ability to take control of individual and collective destinies. He condemned capitalism as a system that alienates the masses. He believed that market forces, not workers, controlled things. People are forced to work for (capitalist) bosses who have full control over all decisions. The workplace, he says, is becoming monotonous, humiliating and suited to machines rather than free and creative people. Ultimately, workers themselves become objects and make decisions based on profit and loss considerations, without regard for human value or needs. Marx concluded that capitalism blocks our ability to create human society. In order to move society forward, workers must reject and promote a market-based society and replace it with a planned democratic society. It is inevitable to advance society throughout history. Class consciousness is the awareness that a social class possesses and its ability to act rationally in its best interests. Class consciousness is necessary before a successful revolution can be led. The short story Harrison Bergeron written by author Kurt Vonnegut was written to criticize the Marxist belief that members of society should strive for equality. He thought it was a dangerous way to pass some of the wealth from richer people to poor people, but it does not eliminate poverty as a whole. If there is not enough wealth, distribution can be hampered. Instead of improving the standard of living for everyone, it actually reduces the incomes of the richest in order to narrow the gap and get closer to the income levels of the poorest. As this provides poorer people with higher income levels, it discourages them from working hard (encourages incompetence). This also creates negative feelings in the minds of hardworking individuals as they do not get any additional incentive to work hard as lazy people are paid the same as them. This has a negative impact on productivity and therefore on economic growth. Although there are many arguments against the practicality of Marxism, it is by far the most just system. This would effectively redistribute higher income levels, thereby promoting a classless society..
