The slave is bought, sometimes at a very high price; in free labor there is no such investment of capital. When the slave is ill, a physician must be paid by the owner; the free laborer defrays his own expenses. The children of the slave must be supported by his master; the free man maintains his own. The slave is to be taken care of in his old age, which his previous habits render peculiarly helpless; the free laborer is hired when he is wanted, and then returns to his home. The slave does not care how slowly or carelessly he works; it is the free man’s interest to do his business well and quickly. The slave is indifferent how many tools he spoils; the free man has a motive to be careful. The slave’s clothing is indeed very cheap, but it is of no consequence to him how fast it is destroyed – his master
must keep him covered, and that is all he is likely to do; the hired laborer pays more for his garments, but makes them last three times as long. The free man will be honest for reputation's sake; but reputation will make the slave none the richer, nor invest him with any of the privileges of a human being – while his poverty and sense of wrong both urge him to steal from his master. A salary must be paid to an overseer to compel the slave to work; the free man is impelled by the desire of increasing the comforts of himself and family. Two hired laborers will perform as much work as three slaves; by some it is supposed to be a more correct estimate that slaves perform only
half as much labor as the same number of free laborers. Finally,
where slaves are employed, manual industry is a degradation to white people, and indolence becomes the prevailing characteristic.
Slave-owners have indeed frequently shown great adroitness in defending this bad system; but, with few exceptions, they base their arguments upon the necessity of continuing slavery because it is already begun. Many of them have openly acknowledged that it was highly injurious to the prosperity of the State.
