The only villages that seem to have success in utilizing their own language are the ones completely cut off from white man's Alaska. They are able to preserve their culture at expense of good & bad of modern world; often they choose this route too.
Alcohol has a way of making it into every village, no matter dry or wet. So you also find that some of villages that suffer the greatest problems (child abuse, violence, deaths from alcohol probs) are the ones that remain cut off from white world; no economy; nothing to do to keep busy; many of members suffer from alcohol addiction. Dying places.
