Our class studied this poem in grade school. The subject of the poem is some guy with a problem, depression if I recall. Its point-of-view is some unnamed “authority” discussing why the subject is experiencing this problem. The authority is puzzled because in pouring over all the information they have on him, his work history, medical records, spending habits, etc. they see no cause for concern.
The point of the poem, of course, is the cause for concern is how much information the authority has on the subject - and by extension each of us, with the implication that we’re all under Big Brother’s microscope.
