"Indigenous people" (read: Skraeling) were in charge, for tens of thousands of years.

They were living in animal hide tents, full of smoke from poorly ventilated fires. They had to abandon the elderly to the elements in times of scarcity because their societies could barely keep the strong alive.

No running water, no electricity, sanitation was pooping ten feet from the camp and then moving when the smell became overpowering.

Anyone wanting to go back to that, including Skraeling, is an naive moron who's never had real life slap them in the face.
