Who caused the class disparity based on ethnic differences in bolivia?

Political tension over social inclusion in Bolivia is enframed by two competing standpoints. One holds that control of the state should be in the hands of the indigenous population, to which the majority of Bolivians belong. Its most radical proponents demand that the non-indigenous minority accept and comply with indigenous notions of economic and social development as well as indigenous understanding of law. The opposing view is that any such reforms would threaten the peace and the country’s territorial integrity.
