Hierarchy is a difficulty for theories of equality, and especially those that define equality in relational or social terms. In ideal egalitarian circumstances it seems that hierarchies should not exist. However, a liberal egalitarian defence of some types of hierarchies is common. Hierarchies of esteem have no further consequences than praise or admiration for valued individual features. Hierarchies of status, with differential reward, can, it is often argued, also be justified when they serve a justified social purpose and meet conditions (...) of genuine equality of opportunity. However, group hierarchies remain problematic, and evidence suggests that they are pervasive in human societies above a subsistence level of production. It has also been argued that group hierarchies are impossible to eliminate, and enormous cost is associated with attempting, and failing, to remove them. However, the perspective of ‘real-world’ political philosophy suggests measures to mitigate group hierarchy, starting with those that are either the easiest to address, the most damaging, or the most consequential.
