No mention of potlatch. > A potlatch is a gift-giving feast practiced by indigenous peoples of the Pacific Northwest Coast of Canada and the United States,[1] among whom it is traditionally the primary governmental institution, legislative body, and economic system. https://en.wikipedia.org/wiki/Potlatch https://en.wikipedia.org/wiki/Potlatch - - - - I have a crude "theory" that economic forms follow density: Small groups, families and small clans, operate more-or-less communally (not political Communism; I mean communal living. Sharing resources, etc.) Larger groups, tribes and neighborhoods, operate more-or-less on barter or favor-balancing. Beyond that, you get money evolving out of long-distance trade, and modern mercantile and financial (as contrasted with "just" economic) systems.
