§ 5. #Child-labor.# All the foregoing arguments are weighed in terms of private incomes and of the value of the products, whereas the main considerations that have of late been influencing legislation and judicial decision in favor of shorter hours have been those of public welfare. The legal limitation of working hours is being treated primarily as a health measure, into the judgment of which is more and more entering a broader conception of the happiness, morality, and opportunities for good citizenship for the worker and his family. In agricultural conditions, such as have prevailed generally in America, there is little need of limiting the hours of work and the age at which children may begin to work. The barefoot boy trudging over clover fields to carry water to the harvesters may be the happier, healthier, and better for his work. Child-labor in agriculture has never become a social "problem" so long as the children work with their own parents at their own homes; but the labor of children for wages, especially in gangs on large farms (as in beet cultivation and cranberry picking) or in canning factories, has exhibited evils as pronounced as any in urban manufacturing conditions. The evil of forcing children into factories was early recognized. The most obvious evils of child-labor are neglect of the child's schooling; destruction of home life; overwork, overstrain, and loss of sleep, with resulting injury to health; unusual danger of industrial accidents; and exposure to demoralizing conditions. The usual assumption that the worker is able to contract regarding the conditions of labor on terms of equality with the employer is most palpably false in the case of children. The child, subject to the commands of his parents and guardians, is not a free agent. Lazy fathers are tempted to support themselves in idleness on the wages of their young children. Often poverty leads the parents to rob their children of health, of schooling, and of the joys of childhood. The competition of child-labor also depresses the wages of adults, and thus the evil grows.
