It is true that in Kentucky the planters are not obliged to pay wages to the slaves whom they employ; but they derive small profits from their labor, whilst the wages paid to free workmen would be returned with interest in the value of their services. The free workman is paid, but he does his work quicker than the slave, and rapidity of execution is one of the great elements of economy. The white sells his services, but they are only purchased at the times at which they may be useful; the black can claim no remuneration for his toil, but the expense of his maintenance is perpetual; he must be supported in his old age as well as in the prime of manhood, in his profitless infancy as well as in the productive years of youth. Payment must equally be made in order to obtain the services of either class of men: the free workman receives his wages in money, the slave in education, in food, in care, and in clothing. The money which a master spends in the maintenance of his slaves goes gradually and in detail, so that it is scarcely perceived; the salary of the free workman is paid in a round sum, which appears only to enrich the individual who receives it, but in the end the slave has cost more than the free servant, and his labor is less productive.
