Edit: A society that has not long since been wiped out because it stood in the way of greed.

That’s seriously moving the goalposts of your original statement.

The Salish Tribes lived in the Pacific NW for ~13500 years, which is a pretty long run. They were quite egalitarian, flatly organized, and lived in balance with the ecosystem. There are other long-lived Native American groups to also consider, such as the Iroquois. See: “The Good Rain” by Timothy Egan, “Braiding Sweetgrass” by Robin Wall Kimmerer. That last book suggestion is a bit more tangential, but the point comes across.

Looking at this with a broader lens, 99.9999+% of all species ever have gone extinct. If you look at societies as a type of species, yeah… the less bellicose, less extractive species will get wiped out by the more avaricious until the ecosystem falls too far out of balance to sustain that behavior.
