Capitalism - Capitalism is an economic system based on the private ownership of the means of production and their operation for profit. Characteristics central to capitalism include private property, capital accumulation, wage labor, voluntary exchange, a price system, and competitive markets. In a capitalist market economy, decision-making and investment are determined by every owner of wealth, property or production ability in financial and capital markets, whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets
Communism - In political and social sciences, communism (from Latin communis, "common, universal") is the philosophical, social, political, and economic ideology and movement whose ultimate goal is the establishment of the communist society, which is a socioeconomic order structured upon the common ownership of the means of production and the absence of social classes, money, and the state.
Feminism - Another example is the feminist movement, which changed the lives of women in the Western world by gaining for them such things as voting rights and greater opportunities for higher education and careers.
