They aren't "renters" in the sense of paying for their property plus a profit for the owner, which is US. They are subsidized for grazing at 80-90% of the cost of private lands, and unlike renters, the families are given right of first refusal generation after generation. In the sense that their lives are subsidized by the rest of us, they (the Bundys and thousands of families more or less like them) are wards of the State, at least to the degree that reservation Indians are.
