 Scholars continue to debate whether Chacoan organization was based on primarily political or primarily ritual considerations.Archeological evidence suggests that the residents of great houses like Chetro Ketl were of a higher social class than those living in smaller settlements, which may indicate a systemic inequality that is considered a hallmark of hierarchal political systems.Others view Chaco as an egalitarian society, with an economy driven by its function as the region's ceremonial center.
