Marxism–Leninism is a political ideology which say that the people should be in control of how their government works and the economy runs. It sees the state and economy as being made up of different classes, like poor, working class, and rich. It also believes that these classes should not exploit each other, and require equality for everyone. To achieve this goal, Marxism–Leninism argues for a socialist society and for a revolution, to overthrow the current capitalist system, where a few people are extremely wealthy, while most do not own anything or have very little. The government should be run by the people, with decisions being made by those who are affected. This will lead to a fair and just society, where all the people can live and work in harmony.
