of social reality. According to Engels, "ideology is a process accomplished by the so-called thinker consciously, it is true, but with a false consciousness. The real motive forces impelling him remain unknown to him; otherwise it simply would not be an ideological process. Hence he imagines false or seeming motive forces." Because the ruling class controls the society's means of production, the superstructure of society (i.e. the ruling social ideas) is determined by the best interests of the ruling class. In The German Ideology, Marx says that "[t]he ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is, at the same time, its ruling intellectual force." The term political economy initially referred to the study of the material conditions of economic production in the capitalist system. In Marxism, political economy is the study of the means of production, specifically of capital and how that manifests as economic activity. This new way of thinking was invented because socialists believed that common ownership of the means of production (i.e. the industries, land, wealth of nature, trade apparatus and wealth of the society) would abolish the exploitative working conditions experienced under capitalism. Through working class revolution, the state (which Marxists saw as a weapon for the subjugation of one class by another) is seized and used to suppress the hitherto ruling class of capitalists and (by implementing a commonly owned, democratically controlled workplace) create the society of communism which Marxists see as true democracy. An economy based on cooperation on human need and social betterment, rather than competition for profit of many independently acting profit seekers, would also be the end of class society, which Marx saw as the fundamental division of all hitherto existing history. Marx saw work, the effort by humans to transform the environment for their needs, as a fundamental feature of humankind. Capitalism, in which the product of the worker's labour is taken from them and sold at the market rather than being part of the worker's life, is therefore alienating to the worker. Additionally, the worker is compelled by various means (some nicer than others) to work harder, faster, and longer. While this is happening, the employer is constantly trying to save on labour costs by paying the workers less and figuring out how to use cheaper equipment. This allows the employer to extract
