Fairness rests on impartiality, not mutualistic cooperation.

Evidence

The target article convincingly argues that mutualistic cooperation is supported by partner choice. However, we will suggest that mutualistic cooperation is not the basis of fairness; instead, fairness is based on impartiality. In support of this view, we show that adults are willing to destroy others’ resources to avoid inequality, a result predicted by impartiality but not by mutualistic cooperation. — Nicolas Baumard, A mutualistic approach to morality, 563
