Two short stanzas, and a lot packed in. The first describes people arriving: a "throng of sad people / carried here by boat." The word "carried" matters. It makes them sound passive, moved along by forces bigger than themselves rather than simply choosing to come. And "sad" is a blunt, unadorned word that doesn't dress up the journey as a happy adventure.
The second stanza shifts to "we," which quietly pulls the speaker into the same story. Land is called "a half-way house," a place that is neither home nor a final destination, somewhere you pass through or stay in without fully settling. The response is almost offhand: "we go drinking." It's hard to say whether that's comfort, escape, or just routine, and the poem leaves that open.
The mood is wry and weary. The title sounds like a proud slogan, but the poem sets it beside loneliness and drift. The speaker doesn't lecture. He just lets the contrast sit there.
