There may be a depression, but the stories in this article aren’t an indication of it. These are symptoms of a completely dysfunctional culture, and are similar to what you find on almost any Indian reservation in North America.
Interesting you should mention reservations...a group of teens and chaperones from our church just got back from a reservation in South Dakota. The conditions for raising a child and providing education were deplorable! Yet the head guy of this group had also traveled to a village in Central America a few years back, where the child were clean, happy, good living conditions, learning, etc. He was deeply saddened by what he saw in SoDak, and exhibited as much while telling us about the experience in front of the congregation!
