The speaker is angry, and the anger is aimed at "us," a group that includes the speaker. The title, "Downsizers," suggests people who cut, trim and reduce, probably workers or costs. The poem pictures a world where the poor are never satisfied by what the powerful offer, not even when a war is on. The line "even in war" hints that war might be expected to bring people together, yet it doesn't change how the poor are treated.
The strangest image is the devil as "our broker." He is a dealer in deals, a middleman for our worst bargains. But he ends up "broke in the street," ruined and furious at "all the blood we drank." The wordplay on "broker" and "broke" is sharp and a little grim. Even the devil is shocked by our appetite. The mood is bitter, sardonic and accusing, and the short lines make it feel clipped and cold. The poem reads like a hard joke that stops being funny at the last line.
