That is because the people had mass genocide waged against them, and now they suffer from the Tourism industry.
By the way: In all the Islands I've been to, The native people LOVE the tourists. Tourism is their livlihood. My sister was amazed because she was shown a video in one of her College classes on how the natives in one of the Islands we visited were oppressed and how WE (the tourists) killed their farming industry. Turns out- when we spoke to a native- IT was their local independent government's corruption.
