I don't support trying to turn back the clock, but modern day hunter gatherers should not be thought of as a reliable picture of past hunter-gatherers. For one, they mostly inhabit some of the lowest quality land since the best land has been taken by industrial society. Past hunter-gatherers would have had their pick of land.
