I wonder how much of that was because of economies of scale (Even if it's forced scale). Plantations are large and have many workers, and can scale without having to worry (to a degree) about retaining workers, since workers are for most intents just machines you invest in and pay to keep up in that system, which allows for easier scaling.

We've seen increasing consolidation of farms into large entities over the centuries, so perhaps this was just a system that made that much, much easier to do.
