I deliberately choice the word 'society', because 'tribe' is an artifact --a pejorative one at that--of western European ethnographic 'disciplines' dedicated to study of so-called primitive people and their customs viz. hagiography of colonial rule in perpetual progress toward perfection of itself.

Vinay Lal, among many other critics of western European historicism beside Foucault, has commented on such language, invented to displace humanity and 'civilization' and political sophistication of any sort in 'the other'.

One humorous, memorable quote in his survey of British India encapsulates the problem for anyone struggling to discard the yoke of the, one, 'progressive' value system:

What's the difference between anthropology and sociology? Sociology is when you study your own people.

Diversity is the key to economic and political evolution.
