A theory that focuses on explaining the feelings of discontent, protest, and collective behavior that individuals or groups have when they compare their situation to what they expect or to what others have, feeling relatively deprived, despite the fact that they get even the bare minimum. That is, feelings of deprivation are not always associated with absolute deprivation (poverty or lack of basic resources), but rather with a gap between what an individual or group actually has and what they think they deserve or should have. The theory of relative deprivation emphasizes that the sense of injustice is stronger than the injustice itself, and that the motivation of individuals and groups is not necessarily a lack of resources, but rather the perception that others enjoy greater privileges or opportunities than they do. It is therefore one of the most important frameworks for understanding the dynamics of collective anger, protests and revolutions in modern societies.
