Labour and expenditure, of which the direct object or effect is the creation of some material product useful or agreeable to mankind. Labour and expenditure, of which the direct effect and object are, to endow human or other animated beings with faculties or qualities useful or agreeable to mankind, and possessing exchangeable value. Labour and expenditure, which without having for their direct object the creation of any useful material product or bodily or mental faculty or quality, yet tend indirectly to promote one or other of those ends, and are exerted or incurred solely for that purpose. The following are partly productive and partly unproductive, and cannot with propriety be ranged decidedly with either class: Labour or expenditure which does indeed create, or promote the creation of, some useful material product or bodily or mental faculty or quality, but which is not incurred or exerted for that sole end; having also for another, and perhaps its principal end, enjoyment, or the promotion of enjoyment. Such are the labour of the judge, the legislator, the police-officer, the soldier; and the expenditure incurred for their support. These functionaries protect and secure mankind in the exclusive possession of such material products or acquired faculties as belong to them; and by the security which they so confer, they indirectly increase production in a degree far more than equivalent to the expense which is necessary for their maintenance. But this is not the only purpose for which they exist; they protect mankind, not merely in the possession of their permanent resources, but also in their actual enjoyments; and so far, although highly useful, they cannot, conformably to the distinction which we have attempted to lay down, be considered productive labourers. Such, also, are the labour and the wages of domestic servants. Such persons are entertained mainly as subservient to mere enjoyment; but most of them occasionally, and some habitually, render services which must be considered as of a productive nature; such as that of cookery, the last stage in the manufacture of food; or gardening, a branch of agriculture. The following are wholly unproductive: Labour exerted, and expenditure incurred, directly and exclusively for the purpose of enjoyment, and not calling into existence anything, whether substance or quality, but such as begins and perishes in the enjoyment. Labour exerted and expenditure incurred uselessly, or in pure waste, and yielding neither direct enjoyment nor permanent sources of enjoyment.
