FWIW -

Northwest coast Indians (US/Canada) had a hunter-gatherer society...

Soc Sci 4 class in 1959, in the person of Clyde Kluckhohn, taught that the Potlatch was a custom of the Kwakiutl Indians. (That would be pronounced "kwock'-ee-OOT'-ll" . ) The tribe got together once a year and threw their possessions into the Columbia River. Whoever threw in the most was the richest and most important person in the tribe.

Not that anyone cares much, three weeks after the discussion has moved on, but it's such a refreshing name...
