If you travel down to the Miami River in Florida, you might come across a micro-economy that centers around “break-bulk” shipping, a labor-intensive system where cargo is moved piece by piece, by people, instead of in giant metal crates and automated equipment.

It’s also a system that runs on orderly chaos — there are no set quotas; people who use the break-bulk system are usually sending thrift store junk; and prices for shipping said junk can be haggled over as they would at a flea market.

But despite its lack of order, it works. It’s also a shipping system that many people in the local Haitian diaspora rely on to send goods to their families and businesses back in Haiti.

Marketplace’s Sabri Ben-Achour spoke to journalist and author Rowan Moore Gerety about his recent reporting dive into the Miami River break-bulk shipping system. They discuss how it worked, how it ties into the Haitian economy and the role cocaine smuggling plays in the system.
