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 [pg 201] 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.
The dependence of wages on the number of the competitors for employment is so far from hard of comprehension, or unintelligible to the laboring-classes, that by great bodies of them it is already recognized and habitually acted on. It is familiar to all trades-unions: every successful combination to keep up wages owes its success to contrivances for restricting the number of competitors; all skilled trades are anxious to keep down their own numbers, and many impose, or endeavor to impose, as a condition upon employers, that they shall not take more than a prescribed number of apprentices. There is, of course, a great difference between limiting their numbers by excluding other people, and doing the same thing by a restraint imposed on themselves; but the one as much as the other shows a clear perception of the relation between their numbers and their remuneration. The principle is understood in its application to any one employment, but
