They live in paradise and make it hell. Despite the use of technology provided by white people, I have the impression that they are still in the Paleolithic because a large part of the population does not farm, does not raise animals, does not live a sedentary lifestyle. They have been on the metal-rich island for 50,000 years, and they have never taken up metal smelting. It can't be said that they didn't smelt at least bronze, because they didn't need it, as they are happy to use objects obtained from white people. There is just something wrong with their brains. Not cogging to the layman's eye has an obvious genetic basis - see the intelligence tag.
