Perfikot's toughness was not out of unreasonable arrogance, nor did she lack the time to properly explain and persuade the plantation owner of the situation.

This is a very primitive and backward production system; never mind the fact that slavery itself offers no incentives for productivity, the mere inefficiency of production methods is enough to show that this should be an obsolete system of production.
