How can we tell that the speaker is comparing and contrasting 2 'worlds' in this poem?
Two 'worlds' or cultures are compared in this poem: the Native American society and the mainstream American society.
The speaker talks about 'hunting' in the wild which Native Americans did, but the father "hunted" in the stockyards. (He worked in a place where herds of cattle are kept.)
Native American boys went on 'vision' quests to find the spiritual meaning of their life but the father was "without a vision" when "he migrated to the city...to work in a packing house." In mainstream American society, a boy becomes a man when he starts working and earning money, which the speaker's father did. The maturity that the father achieved was not the same as in Native American culture.
