Status maintains and stabilizes social stratification. Mere inequality in resources and privileges is likely to be perceived as unfair and thus prompt retaliation and resistance from those of lower status, but if some individuals are seen as better than others (i.e., have higher status), then it seems natural and fair that high-status people receive more resources and privileges. Historically, Max Weber distinguished status from social class, though some contemporary empirical sociologists combine the two ideas to create socioeconomic status or SES, usually operationalized as a simple index of income, education and occupational prestige.
