I'm afraid I disagree with your last statement. It is possible that perhaps I've just been so fortunate that all the people I've ever come across are mostly similar in what they want from life. It seems to be the same all over the world: general well being, safety and security of their family and their future.

People disagree on priorities and not everyone's incentives are the same but I've never felt that by default people are bad. I'm no scientist (or sage) and just an average human. So, this is just how I see things and not based on expert scientific inquiry. Make of it what you will.
