The speaker of "Promoter" seems to be a man who has settled into comfortable domestic life and is not entirely at ease with what that comfort rests on. The poem opens with a fattening hog, which becomes "our common weather," as if growth, appetite and plenty were the climate everyone lives in. The hog is an image of getting fat on abundance, and the poem treats that as ordinary, almost unavoidable.
Then the speaker turns to himself. He "found a home" after giving his wife a child, and the repeated "a child, a child" has a slightly dazed, ticking quality, as though family life were something to be counted or delivered. The last line is the sharpest: after supper, his ink is "a mother to greed." Judging by the title, he may be someone who sells or pushes things with words, and the poem suggests his writing feeds desire rather than satisfying it.
The mood is dry, wry and a little uneasy. Nothing is stated outright, but contentment and guilt sit side by side.
