By what means, then, is poverty to be contended against? How is the evil of low wages to be remedied? If the expedients usually recommended for the purpose are not adapted to it, can no others be thought of? Is the problem incapable of solution? Can political economy do nothing, but only object to everything, and demonstrate that nothing can be done? Those who think it hopeless that the laboring-classes should be induced to practice a sufficient degree of prudence in regard to the increase of their families, because they have hitherto stopped short of that point, show an inability to estimate the ordinary principles of human action. Nothing more would probably be necessary to secure that result, than an opinion generally diffused that it was desirable. But let us try to imagine what would happen if the idea became general among the laboring-class that the competition of too great numbers was the principal cause of their poverty. We are often told that the most thorough perception of the dependence of wages on population will not influence the conduct of a laboring-man, because it is not the children he himself can have that will produce any effect in generally depressing the labor market. True, and it is also true that one soldier’s running away will not lose the battle; accordingly, it is not that consideration which keeps each soldier in his rank: it is the disgrace which naturally and inevitably attends on conduct by any one individual which, if pursued by a majority, everybody can see would be fatal. Men are seldom found to brave the general opinion of their class, unless supported either by some principle higher than regard for opinion, or by some strong body of opinion elsewhere. If the opinion were once generally established among the laboring-class that their welfare required a due regulation of the numbers of families, the respectable and well-conducted of the body would conform to the prescription, and only those would exempt themselves from it who were in the habit of making light of social obligations generally; and there would be then an evident justification for converting the moral obligation against bringing children into the world, who are a burden to the community, into a legal one; just as in many other cases of the progress of opinion, the law ends by enforcing against recalcitrant minorities obligations which, to be useful, must be general, and which, from a sense of their utility, a large majority have voluntarily consented to take upon themselves.
