Anthropological theories
Most if not all anthropologists dispute the "universal" nature of social stratification, holding that it is not the standard among all societies. John Gowdy (2006) writes, "Assumptions about human behaviour that members of market societies believe to be universal, that humans are naturally competitive and acquisitive, and that social stratification is natural, do not apply to many hunter-gatherer peoples. Non-stratified egalitarian or acephalous ("headless") societies exist which have little or no concept of social hierarchy, political or economic status, class, or even permanent leadership."
