Rh with advantage to both, in comparison with raising the amount by taxation, since taxes, especially when heavy, are almost always partly paid at the expense of what would otherwise have been saved and added to capital. Besides, in a country which makes so great yearly additions to its wealth that a part can be taken and expended unproductively without diminishing capital, or even preventing a considerable increase, it is evident that even if the whole of what is so taken would have become capital, and obtained employment in the country, the effect on the labouring classes is far less prejudicial, and the case against the loan system much less strong, than in the case first supposed. This brief anticipation of a discussion which will find its proper place elsewhere, appeared necessary to prevent false inferences from the premises previously laid down.

§ 9.We now pass to a fourth fundamental theorem respecting Capital, which is, perhaps, oftener overlooked or misconceived than even any of the foregoing. What supports and employs productive labour, is the capital expended in setting it to work, and not the demand of purchasers for the produce of the labour when completed. Demand for commodities is not demand for labour. The demand for commodities determines in what particular branch of production the labour and capital shall be employed; it determines the direction of the labour; but not the more or less of the labour itself, or of the maintenance or payment of the labour. These depend on the amount of the capital, or other funds directly devoted to the sustenance and remuneration of labour.

Suppose, for instance, that there is a demand for velvet; a fund ready to be laid out in buying velvet, but no capital to establish the manufacture. It is of no consequence how great the demand may be; unless capital is attracted into the occupation, there will be no velvet made, and consequently none bought; unless, indeed, the desire of the intending purchaser
