The last time I read the literature, hunter-gatherers have a relatively high proportion of leisure time.By providing a stable, reliable, and (over-)abundant source of food and resources, the move from hunter-gatherer to agriculture paved the way for civilization as we know it by providing time and resources for people to do things beyond the bare necessities to survive.
And who invented hunting? Gathering? Child-rearing? Art? Religion?which hunter-gatherer society invented the aqueduct? Or paved roads? Or metalsmithing beyond the absolute most basic? None of these existed before agriculture allowed them to exist, and all allowed those societies to prosper where others didn't.
It seems rather banal to point out that different technologies are feature of different forms of social organisation. I don't see what it is supposed to tell us, eg, about the "inferiority" of Orcs, or of (some) humans.
This is nonsense. The idea that hunger-gatherers are "doomed" is nothing but genocidal fantasy.agrarian societies are, over time, going to develop beyond what hunter-gatherer societies can manage; and unless the h-g's have a counter (in the case of Orcs, this counter would be sheer numbers and aggression) the h-g's are eventually doomed.
