Society is comfortable and supportive, as long as one conforms to it. Neighbours provide vital social support against hostile members of other clans and language groups. One lives on one's own ground, the home of one's ancestral spirits, and one understands the spirits of the local land, rivers, trees, stones, etc., even if some are antagonistic. This is where the family nasara, or sacred dancing ground, is located. The money economy doesn't have much influence in the village.
Housing comes from the bush, and food is grown in the garden.
I don't think so. There is a lot of stress in rural Vanuatu. Despite the very visible presence of Christianity, one is constantly threatened by enemy spirits of what Westerners consider inanimate objects, and one's social competitors within and outside the village are liable to pay a kleva to cause harm through sorcery. Village bigmen, including the village representative of the locally-favoured national political party, can demand favors. Incest is not unknown.
