increase of material products is its ultimate consequence. Thus, labour expended in the acquisition of manufacturing skill, I class as productive, not in virtue of the skill itself, but of the manufactured products created by the skill, and to the creation of which the labour of learning the trade is essentially conducive. The labour of officers of government in affording the protection which, afforded in some manner or other, is indispensable to the prosperity of industry, must be classed as productive even of material wealth, because without it, material wealth, in anything like its present abundance, could not exist. Such labour may be said to be productive indirectly or mediately, in opposition to the labour of the ploughman and the cotton-spinner, which are productive immediately. They are all alike in this, that they leave the community richer in material products than they found it; they increase, or tend to increase, material wealth.
§ 4.By Unproductive Labour, on the contrary, will be understood labour which does not terminate in the creation of material wealth; which, however largely or successfully practised, does not render the community, and the world at large, richer in material products, but poorer by all that is consumed by the labourers while so employed.
All labour is, in the language of political economy, unproductive, which ends in immediate enjoyment, without any increase of the accumulated stock of permanent means of enjoyment. And all labour, according to our present definition, must be classed as unproductive, which terminates in a permanent benefit, however important, provided that an increase of material products forms no part of that benefit. The labour of saving a friend's life is not productive, unless the friend is a productive labourer, and produces more than he consumes. To a religious person the saving of a soul must appear a far more important service than the saving of a life; but he will not therefore call a missionary or a
