Now it's probably entirely possible to develop institutions that can resolve these problems in an egalitarian and peaceful fashion. The problem is such solutions require experimentation before you get them right. — Echarmion
Actually (resurrector!) maybe not.
The Cree in Canada were a traditional immediate return hunter-gatherer tribe centred around kinship groups. They were quite expansive, too much so to share a gazelle or whatnot, but a) anyone could hunt where they liked, although they tended to do so in their own hunting grounds, and b) a sophisticated network of sharing established itself across the whole Cree area.
The Cree lived mainly on beaver (fnar) and traded beaver and (iirc) fox fur. In the 19th century, white trappers started devastating Cree hunting grounds, bringing their shares prey to local extinction or close to before moving onto the next hunting ground.
The Cree tried to get ahead of the white trappers by essentially becoming a delayed return group, exerting great effort to exhaust so much pray that trapping wasn't worthwhile. Interestingly, they had no concept of territory. They saw trappers as tricky competitors, not invaders, and tried to win the competition.
What happened next is that the state of Quebec stepped in around 1920. Various anthropologists raised concerns about the threat to the Cree, while various fur traders highlighted the threat to stocks. Quebec made a call: they carved up the area, with each hunting ground being the territory of the kinship group that lived there (thinking they were helping the Cree protect private property), banned white trappers, and insisted that an elected member of each group note and report on the health of beaver stocks, the presence of trappers, and invasion by any outside Cree group.
Quebec gave them millions in payment, settlement, and to exchange areas for development, as well as giving jobs to an increasing number of Cree people. Cree could get bank accounts to hide wealth, acquire vehicles, buy pretty much whatever. By the 80s, almost half of labouring Cree were wage-earners.
One would expect this would destroy the Cree way of life, however kindly meant. In fact, they seem to have absorbed their relationship with European Canadians without much damage. It is thought that probably some Cree are hiding wealth, but they can't do much with it since any overt wealth is seen as bad. Each household generally has a mixture of wage-earners and hunters, so so far there hasn't been much in the way of inequality in wealth aggregation. The beaver stocks returned to health entirely down to the management of the Cree, since they ignored Quebec's request, hunted wherever they liked, allowed hunting by whoever in their own grounds, and just made up the numbers they sent to the white man, recovering an entire ecology, their own economy, without changing their ways.
The Cree have managed to introduce delayed return living (wage-earning) through relations with a capitalist European power without becoming non-egalitarian. Part of this I guess is down to them not being immediate- or delayed-return exclusively, but rather operating a novel pluralism.
Interestingly, the Cree initially extended their egalitarianism to the white man, but now do not. In fact, one could argue that they're taking Quebec for everything they can. Their non-egalitarian attitude stems from difference, a lot like ours: the white man is not like Cree, and must be dealt with differently. It's not hostile, and this difference in absorbed into Cree way of life, but at the same time this new way of life is seen as additional and kept at some distance to Cree-ness.
It's quite remarkable. If anyone's interested, I got most of this from Colin Scott's 'Property, Practice, and Aboriginal Rights Among Quebec Cree Hunters', an essay from the book Hunters and Gatherers Volume II: Property, Power and Ideology but I imagine any decent anthro review article on the Cree would be just as interesting.
So it isn't just a case of immediate return tending to be flipped by environmental factors and opportunistic power players. While it's true to say that the Cree aren't really immediate return anymore, nor are they delayed return or non-egalitarian.
Pluralism was the key for the Cree, which, as a pluralist myself, is a nice surprise. Anyway, long post on niche subject in dead thread for an audience of probably just me, sorry.
