My great-great uncle Richard lived to be 98 years old. He never owned a car although he was a man of considerable means. When he was too old and feable to mount his trusty steed, he trained it to kneel so he could continue to live in an antiquated way. What does this have to do with native tribes anywhere? Not a whole lot, but it does highlight two points.
Uncle Richard wasn't good or bad, right or wrong. He had lived long enough to fit in each category at least once. Every persons opinion of him was unique. I suppose he was "right and good" in his own mind, which is the only one that mattered to him. Same as all antiquated people, natives, primitives, etc.
The "advantage" of technology is not always invited or wanted. It is cumbersome to some minds. I don't think that Killdeer, Ken or Dave are fantasizing. What they represent is individuals that would prefer to live with their minds unencumbered by modern "advantages". Sorry if this observation is incorrect.
It applies to these heathen savages (intentional irony in the nomenclature) in this way, they do not have a choice and it is indeed sad. Having the ability to see their situation from the outside in, I don't think they are going to benefit from modern society. I don't wish them to see the days of highway traffic, punching a clock, taxes and such ilk. Are they good or bad? Right or wrong? It probably doesn't matter what we think based on our perception. Their reality is different. Use the advantage? I suppose they will - to their damnation. Long live the free soul!
