The poem seems to be spoken by a group of people, a "we," who arrive in a place that is described as free of poverty. That description sounds like an irony. A country "where no poor live" may be one that has pushed its poor out of sight, or one that cannot imagine them as belonging. The second stanza turns into what looks like an accusation: the newcomers are said to "eat all our rent and debts," a strange, tangled phrase that reads like the exaggerated complaint of people who resent outsiders.
The final stanza is the sharpest. The speakers admit they have "no papers," meaning no legal permission to be there, but then add "it being night," as if darkness blurs the rules. The closing question, "whose land is it," is left open. Judging by the imagery, the mood is uneasy and hushed, a mix of vulnerability and quiet defiance. The poem doesn't answer the question; it makes the reader sit in the dark with it.
