You'd have to be pretty naive to think that primitive people are happier or more in tune with nature. The only reason why any piece of technology is adopted on a large scale is because it takes care of some human need. Many primitive peoples practice cannibalism and they are always squabbling and killing each other over limited resources.Their populations are small because their methods of resource extraction are inefficient and they are constantly dying frim preventable diseases and starvation. They are uneducated and come up with all sorts of convoluted theories about spirits and curses to explain phenomenon in the natural world.
