From my experience, people are happy with their lives until they see how the other half lives. So you might find a tribe in a hard to reach area somewhere in this world that is happy to live the way they live until they come across people who seemingly have it better than them or have something they want. You'll find that happening far back into history... that's why all the wars, invading other countries, colonialism, etc.
And re. God... watching Blood Diamond right now, and can't help but quote Leonardo di Caprio's character. In some areas of the world, people may agree with him: God left this place a while ago.
