Precisely! But I would argue that homogeneity (in beliefs, culture, SES) is what defines the tribe. A heterogenous, divided group would not be a cohesive tribe, and therefore would not have a unifying status hierarchy. Old money and new money are separate tribes, and each status signals to ingroup members in profoundly different ways.
