Social oppression refers to oppression that is achieved through social means and that is social in scope—it affects whole categories of people. This kind of oppression includes the systematic mistreatment, exploitation, and abuse of a group (or groups) of people by another group (or groups). It occurs whenever one group holds power over another in society through the control of social institutions, along with society's laws, customs, and norms. The outcome of social oppression is that groups in society are sorted into different positions within the social hierarchies of race, class, gender, sexuality, and ability. Those in the controlling, or dominant group, benefit from the oppression of other groups through heightened privileges relative to others, greater access to rights and resources, a better quality of life, and overall greater life chances. Those who experience the brunt of oppression have fewer rights, less access to resources, less political power, lower economic potential, worse health and higher mortality rates, and lower overall life chances.
