Quizplus · Accepted Answer

The rising value of slaves made it profitable for slaveowners to take better care of them. As slavery became more profitable in the American South, slaveowners were more inclined to invest in the health and well-being of their slaves to ensure they would be able to provide a return on their investment. In contrast, in other regions where slavery was less profitable, slaveowners had less incentive to take care of their slaves.
