To a Soviet person, used to the nationality policy of the USSR, all the mistakes of the American government's Indian policy are evident from the first glance. The mistakes are, of course, intentional. The fact of the matter is that in Indian schools, class is conducted exclusively in English. There is no written form of any Indian language at all. It's true that every Indian tribe has its own language, but this doesn't change anything. If there were any desire to do so, the many American specialists who have fallen in love with Indian culture could create Indian written languages in a short time. But imperialism remains imperialism.
