Read the passage from Sugar Changed the World.

Workers could not leave the plantation unless they had a pass. And if they did decide to explore on their own, without permission, they could be thrown in jail, sentenced to hard labor, or lose some of their hard-earned wages. A charge of "idling" in the fields could result in the loss of a whole week's wages. Worse, if they dared rebel or protest, their contract could be transferred to another estate. And there were still complaints of flogging or mysterious deaths. Life, as the historian Hugh Tinker noted, was like being a prisoner on parole.
