It does talk about leaders not owning their wealth as it was owned collectively by the tribe. No, it does not mention this specific tribe. I can’t find my anthro book either.

I could have remembered it wrong. I spent some more time poking around the Internet this morning about chiefdoms. I still couldn’t find the specific tribe, but I learned some other interesting things.

There does seem to be some romanticizing small groups and the concept of tribal communism. So there is definitely something to support your skepticism.
