But, well, here's the thing. South Dakota, arid though it might be, is not Oklahoma. South Dakota's Indians are mostly Sioux-- the members of the Lakota/ Nakota/ Dakota nations from which the state takes its name. They have been progressively crowded onto smaller and smaller portions of their ancestors' homelands as a result of gold rushes, wars, thefts, and allotments and partitions. But they have not been "exiled" from their homeland, and strange, arid South Dakota is not strange to them.
There's been plenty of bad policy directed at Indians-- but it's not the same bad policy everywhere.
