Five short lines, one sentence, and a whole political economy folded into it. Dave Bonta's "Mercantilism" works like a deadpan definition: the title names an economic doctrine, in which a state grows rich by trading, hoarding wealth, and backing its commerce with force, and the poem then says what that looks like when stripped of polite language. Its answer is that war, trade, and execution together make up a "commonwealth," and the profit from all of it comes from something "cheap."
The grammar carries much of the meaning. The subject is a list of three nouns, "the war, the exchange / and the hangman," and the verb, "make," doesn't arrive until line four. Between subject and verb sits the phrase "constituting / a commonwealth," so the reader has to wait through the whole definition of the state before learning what it does. When the verb comes, it is a plain business verb: "make a profit." The sentence builds a grand structure and then reveals it as a bookkeeping exercise.
The list is cleverly ordered. "The exchange," the marketplace, sits between "the war" and "the hangman," one a tool of conquest and the other of punishment. Trade is not presented as a neutral middle ground but as something hemmed in by violence on both sides. The three figures also cover the main powers of a state: the army, the economy, and the law's last resort. The poem suggests that a country's wealth depends on all three working together.
Then there is the word "commonwealth." Its roots are "common" and "wealth," a shared good. Bonta lets the word sit alone on its short third line, as if inviting us to admire it, and then undercuts it. What is held in common here is machinery that kills and trades, and the wealth that results doesn't sound shared at all. The word "constituting," with its echo of a constitution, adds a legal solemnity that the rest of the sentence quietly mocks.
The ending is the strangest and most memorable part. "A cheap / piece of star" leaves us with an image we can't quite pin down, and that vagueness seems deliberate. "Star" could point to something distant and beautiful, now cut up and sold in pieces. It might hint at a coin, though that is an inference, since "piece" also appears in the old phrase "pieces of eight." It could simply mean any prize big enough to justify the trouble. Whichever reading we choose, the contrast is sharp. Wars and hangings are costly in human terms, yet what they buy is called "cheap." The adjective cuts two ways, meaning both low-priced and of little worth, and the poem leaves us wondering who is being cheated.
The line breaks add to the effect. "Cheap" stays at the end of line four, hanging before the final fragment "piece of star" completes it. The lines shrink toward the finish: roughly five syllables, then eight, then four, then seven, then three. The poem thins out as it goes, ending on a small, bright, almost throwaway phrase. There is no rhyme, but the opening and closing stressed words, "war" and "star," share an ending sound and a long, open vowel. That near-echo links the poem's two extremes, one earthly and violent, the other celestial and clean, and suggests that the first has been feeding on the second.
The poem is significant because of how much it does in so little space. It makes no speech and offers no outrage. Its tone is flat, almost bureaucratic, as if the speaker were reading an accounting entry aloud. That restraint is where its force comes from. A student might notice how often serious arguments about power rely on loud language, and how quietly this one makes its case instead. By the time we reach "star," we realize we have been listening to a ledger, and the poem leaves us to decide whether we are comfortable with what it adds up.
