"In process of time, the robber, or slaveholding, class—who had seized all the lands, and held all the means of creating wealth—began to discover that the easiest mode of managing their slaves, and making them profitable, was not for each slaveholder to hold his specified number of slaves, as he had done before, and as he would hold so many cattle, but to give them so much liberty as would throw upon themselves (the slaves) the responsibility of their own subsistence, and yet compel them to sell their labor to the land-holding class—their former owners—for just what the latter might choose to give them. Of course, these liberated slaves, as some have erroneously called them, having no lands, or other property, and no means of obtaining an independent subsistence, had no alternative—to save themselves from starvation—but to sell their labor to the landholders, in exchange only for the coarsest necessaries of life; not always for so much even as that."
