There are limits to everything, even the best intentions of educational technology when contrasted to the changing harsh physical reality of North American schools. Poems are voices and, in this case, the voice of a cynical speaker who is hip to brutal reality. (BTW/ Frost often used the voices of characters in his best work.)
Poems are also ideas and usually express themes as this one does. The interesting challenge for the poet is choose the specific words, terms, and tones to advance whatever ‘thesis’.
