Actually, Nels, your ancestors came across the land bridge from Asia, they didn't just appear here.  As far as modern services in bush villages--the economies of scale simply don't justify the cost.  Running water and central sewage for 50-100 homes is just too much on a per home basis.  Not to mention commercially viable broadband; my monthly bill in Anchorage is $175...I can't imagine what GCI would have to charge to pipe it out to the bush without significant gov't support.
