Right. Same thing happened in the US west about 100 years ago. Remember “Don’t Fence Me In” and the range wars? Open range cattle drivers are hunter-gatherers.
I thought more of the Injuns.
Guys who raise sheep, as distinct from just following them around, are also Neolithic farmers (and herdsmen).
Hunter/gatherers live on dried meat from game and fish, low-glycemic wild berries and fruit, and root crops commonly found near game trails.
From about 1648 to maybe 1830 there were numerous American Indian groups throughout the more settled areas of what is now the United States who made their living HUNTING GAME for the farmers. Some of this was done on an industrial scale! It's sometimes forgotten that their forebears were, themselves, neolithic farmers ~ not mesolithic hunter/gatherers.
The mesolithic types are still here and live in the North where grass doesn't grow. They make a living as hunting or fishing guides, or off the Canadian dole. I guess they have to toss up a tipi from time to time to maintain their eligibility, but they still effectively occupy the greater part of North America WITH EASE!
