produce more of the commodity, and may by an indirect effect in causing an increase of capital, produce an eventual increase of the remuneration of the labourer.
The demand for commodities is a consideration of importance rather in the theory of exchange, than in that of production. Looking at things in the aggregate, and permanently, the remuneration, of the producer is derived from the productive power of his own capital. The sale of the produce for money, and the subsequent expenditure of the money in buying other commodities, are a mere exchange of equivalent values for mutual accommodation. It is true that, the division of employments being one of the principal means of increasing the productive power of labour, the power of exchanging gives rise to a great increase of the produce; but even then it is production, not exchange, which remunerates labour and capital. We cannot too strictly represent to ourselves the operation of exchange, whether conducted by barter or through the medium of money, as the mere mechanism by which each person transforms the remuneration of his labour or of his capital into the particular shape in which it is most convenient to him to possess it; but in no wise the source of the remuneration itself.
§ 10.The preceding principles demonstrate the fallacy of many popular arguments and doctrines, which are continually reproducing themselves in new forms. For example, it has been contended, and by some from whom better things might have been expected, that the argument for the income-tax, grounded on its falling on the higher and middle classes only, and sparing the poor, is an error; some have gone so far as to say, an imposture; because in taking from the rich what they would have expended among the poor, the tax injures the poor as much as if it had been directly levied from them. Of this doctrine we now know what to think. So far, indeed, as what is taken from the rich in taxes, would, if not so taken, have been saved and converted into capital, or even expended in
