Im kind of sad that tribes, who have never been exposed to the modern world, get exposed to the damaging effects of materialism. It reminds me of that film "The gods must be crazy" [0]
The moral of the story is that things, when they are coveted, can destroy our humanity. I feel like we are destroying ourselves with modernity and to bring that to a culture like this is dangerous.
Jared Diamond speaks of this in one of his book (I think "Collapse", but I may be wrong), and highlights how we romanticize the pre-modern world, but we have the clear example of people in PNG who are absolutely super happy to abandon it and join the modern one.
(the modern world has plenty of problems, of course)
This isnt romanticizing premodern world. Modern doesn't equal better, but I understand the knee jerk reaction to calling out the serious problems with our current society that nobody wants to face.
