And a courageous woman. Great work.
I know change is inevitable. Does anyone wonder if these cultures are better or worse off as the change comes?
I certainly don't think they get any "happier".
I agree Doug, and suspect that most cultures, tribes, or societies will, by natural pressures, stabilize in a condition of reasonable happiness if left alone by outsiders. Just as a healthy individual will, if possible, conduct themselves to achieve the most happiness, so will the individuals in a tribe or region.
Happiness is threatened when an outside entity attempts to influence, assist, or exploit the peoples in the tribe or region. The insensitive or ignorant invasion will disrupt the natural balance or mechanism which has for centuries served the people and given them the much needed stability and happiness. The best source for achieving happiness comes from those in need of it, and not from those without, who typically wish to exploit or force upon the peoples unworkable remedies or solutions.
