I don't think you can compare Manang with Indian Reservation; you can compare it with a state whose head can be a person of any race or color depending on capability.
I glanced at that thesis and I don't think there is anything special there. The guy talks about how indegenious people around the world suffer; and it feels emotional to read about it.
But the real questions that should be asked are:
Is the state giving preferential treatment to certain race or color? What actions are taken by state to keep down persons of cetain race and color?
