There is a tribe in Ecuador, the Huaorani. They were only brought into contact with the world 70 years ago. Because they live at the equator, they never needed to think ahead to store food over the winter. They could see that the oil companies were destroying their land by polluting it with spoil from operations, cutting down swaths of the forest, etc, and they became activists pushing back against this; but a good hunter who can hand out food to others is very highly regarded in their culture, so they would queue for handouts from the oil companies and became dependent on them, doing low-wage work. When I read about this years ago, I thought that people from modern cultures would not be so naive, but I see that I was wrong.
