"Migrations" by Dorian Merina

I interpreted "Migrations" by Dorian Merina as a connection between high economic demands and slavery.  The poem lists many goods being brought across the ocean, from "untwisted silk" to "sapphires"  to "cherries."  The people working on the boat, bringing the goods to the greedy buyers "sleep or fight to sleep" and "awake to the damp air" with "salt in the throat and cough to awake to the dark night," which is a constant pattern for them.  This poem reminds me of the movie Blood Diamonds.  The ignorant buyers of goods either are not aware of or pay no attention to the harsh realities others live in to ensure they can have diamonds, "quantities of velvets," or any other product.  I did not understand the purpose of the list of "[words] like achuete" and "tacayo."  The most effective part of the poem to me was "On the boats come the blood, the blood, the blood."  This made me imagine that along with the goods being shipped across the ocean is the blood of the slaves, slaves who are toiling to help make the materialistic, ignorant middle/upper class people happy.
