2. Property necessary to life, but only producible by labour, and of which the possession is morally connected with labour, so that no person capable of doing the work necessary for its production has a right to it until he has done that work:--"he that will not work, neither should he eat." It consists of simple food, clothing, and habitation, with their seeds and materials, or instruments and machinery, and animals used for necessary draught or locomotion, etc. It is to be observed of this kind of property, that its increase cannot usually be carried beyond a certain point, because it depends not on labour only, but on things of which the supply is limited by nature. The possible accumulation of corn depends on the quantity of corn-growing land possessed or commercially accessible; and that of steel, similarly, on the accessible quantity of coal and ironstone. It follows from this natural limitation of supply that the accumulation of property of this kind in large masses at one point, or in one person's hands, commonly involves, more or less, the scarcity of it at another point and in other persons' hands; so that the accidents or energies which may enable one man to procure a great deal of it, may, and in all likelihood will partially prevent other men procuring a sufficiency of it, however willing they may be to work for it; therefore, the modes of its accumulation and distribution need to be in some degree regulated by law and by national treaties, in order to secure justice to all men. Another point requiring notice respecting this sort of property is, that no work can be wasted in producing it, provided only the kind of it produced be preservable and distributable, since for every grain of such commodities we produce we are rendering so much more life possible on earth.[23] But though we are sure, thus, that we are employing people well, we cannot be sure we might not have employed them _better_; for it is possible to direct labour to the production of life, until little or none is left for that of the objects of life, and thus to increase population at the expense of civilization, learning, and morality: on the other hand, it is just as possible--and the error is one to which the world is, on the whole, more liable--to direct labour to the objects of life till too little is left for life, and thus to increase luxury or learning at the expense of population. Right political economy holds its aim poised justly between the two extremes, desiring neither to crowd its dominions with a race of savages, nor to found courts and colleges in the midst of a desert.
