It is always easy to overwork an analogy, and yet the economist who for years insisted that slave labor continually and arbitrarily limited the wages of free labor and was therefore a detriment to national wealth was a forerunner of the economist of to-day who points out the economic basis of the social evil, the connection between low wages and despair, between over-fatigue and the demand for reckless pleasure. Before the American nation agreed to regard slavery as unjustifiable from the standpoint of public morality, an army of reformers, lecturers, and writers set forth its enormity in a never-ceasing flow of invective, of appeal, and of portrayal concerning the human cruelty to which the system lent itself. We can discern the scouts and outposts of a similar army advancing against this existing evil: the physicians and sanitarians who are committed to the task of ridding the race from contagious diseases, the teachers and lecturers who are appealing to the higher morality of thousands of young people; the growing literature, not only biological and didactic, but of a popular type more closely approaching "Uncle Tom's Cabin." Throughout the agitation for the abolition of slavery in America, there were statesmen who gradually became convinced of the political and moral necessity of giving to the freedman the protection of the ballot. In this current agitation there are at least a few men and women who would extend a greater social and political freedom to all women if only because domestic control has proved so ineffectual.
