Our country is a theatre, which exhibits, in full operation, two radically different political systems; the one resting on the basis of servile or slave labor, the other on voluntary labor of freemen. The laborers who are enslaved are all negroes, or persons more or less purely of African derivation. But this is only accidental. The principle of the system is, that labor in every society, by whomsoever performed, is necessarily unintellectual, grovelling and base; and that the laborer, equally for his own good and for the welfare of the State, ought to be enslaved. The white laboring man, whether native or foreigner, is not enslaved, only because he cannot, as yet, be reduced to bondage. You need not be told now that the slave system is the older of the two, and that once it was universal. The emancipation of our own ancestors, Caucasians and Europeans as they were, hardly dates beyond a period of five hundred years. The great melioration of human society which modern times exhibit, is mainly due to the incomplete substitution of the system of voluntary labor for the one of servile labor, which has already taken place. This African slave system is one which, in its origin and in its growth, has been altogether foreign from the habits of the races which colonized these States, and established civilization here. It was introduced on this continent as an engine of conquest, and for the establishment of monarchical power, by the Portuguese and the Spaniards, and was rapidly extended by them all over South America, Central America, Louisiana, and Mexico. Its legitimate fruits are seen in the poverty, imbecility, and anarchy which now pervade all Portuguese and Spanish America. The free-labor system is of German extraction, and it was established in our country by emigrants from Sweden, Holland, Germany, Great Britain and Ireland. We justly ascribe to its influences the strength, wealth, greatness, intelligence, and freedom, which the whole American people now enjoy. One of the chief elements of the value of human life is freedom in the pursuit of happiness. The slave system is not only intolerable, unjust, and inhuman, toward the laborer, whom, only because he is a laborer, it loads down with chains and converts into merchandise, but is scarcely less severe upon the freeman, to whom, only because he is a laborer from necessity, it denies facilities for employment, and whom it expels from the community because it cannot enslave and convert into merchandise also. It is necessarily improvident and ruinous, because, as a general truth, communities prosper and flourish, or droop and decline, in just the degree that they practise or neglect to practise the primary duties of justice and humanity. The free-labor system conforms to the divine law of equality, which is written in the hearts and consciences of man, and therefore is always and everywhere beneficent.
