Why is it so important to Kino to make sure that Coyotito receives an education?

Kino knows that education is the key to Coyotito's future and his hope for getting out of his oppressed situation. Only those who are educated can have a future that is different from those who will stay in the Indian, undereducated class that is and has been oppressed for years.
