It, nevertheless, but ill becomes the home British to say much about the United States’ slavery, or, indeed, about any slavery. The causes which operate to promote or prevent direct slavery, have never, that I am aware of, been clearly pointed out. Slaves (direct) are found only where land is cheap. When the land, from its redundancy in proportion to population, as in America, is of little or no value, the whole property consists of labour, or the produce of labour; and the covetous man not being able to satisfy his lust for riches by the produce of his own labour, has no other way of gratifying it but by obtaining possession of the persons of his fellow-men, and compelling them to labour the otherwise unprofitable ground for his emolument; and this he finds profitable, because the produce of labour, even of slave-labour, in this favourable field for production, is more than sufficient to support his slaves as reproductive labouring-stock, or to purchase new ones should they wear out. On the reverse, slaves (direct) are not found when the land has been all occupied, and has reached any considerable value or rental. Wherever this has taken place, and population has become dense, hired or piece-labour becomes more profitable than slave-labour, and drives it from the field. The reason of this is obvious: man, in a state of comparative liberty of action, has more of mental energy to stimulate and carry on his corporeal exertions, and to direct them to more profitable effect, than when under direct slavery, while at the same time he can be maintained at less cost as a reproductive animal when in semblance free. Besides, when the land has been all taken up, and has come into the hands of a small number of the community, these, from being the possessors of property, generally obtain the governing power, and form a land-aristocracy class. They proceed to legislate and levy taxation in the most partial and unjust manner to forward their own selfish interests, they secure the land-property to themselves and their posterity, and, by taking advantage of the poverty and necessity for food of the labouring population, make out to obtain a more complete command over their labour, and more power to render them subservient to their pleasure and luxury, than if the working population were slaves direct.
