Sociologists recognize that social stratification is a societal wide method that makes inequalities apparent. While there are always inequalities between individuals, sociologists are interested in larger social patterns. Stratification is not about individual inequalities, but about systematic inequalities based on group membership, classes, and the like. No individual, rich or poor, can be blamed for social inequalities. The structure of society affects a person’s social standing. Although individuals may support or fight inequalities, social stratification is created and supported by society as a whole.
