The idea was to keep your slaves healthy enough to keep working hard on your plantation. It's the same idea in play today only it's not abducted people from Africa, it's people enslaved all over the planet (irregardless of race) and the plantation owners will have their crops made where ever it is the most profitable for them to do so. Profit over people is the mantra of the greedy sociopath. "people over profit" is worth fighting for.
