ARTICLE III.—Taxes upon the Wages of Labour.
The wages of the inferior classes of work men, I have endeavoured to show in the first book are everywhere necessarily regulated by two different circumstances; the demand for labour, and the ordinary or average price of provisions. The demand for labour, according as it happens to be either increasing stationary or declining; or to require an increasing, stationary, or declining population, regulates the subsistence of the labourer, and determines in what degree it shall be either liberal, moderate, or scanty. The ordinary average price of provisions determines the quantity of money which must be paid to the workman, in order to enable him, one year with another, to purchase this liberal, moderate, or scanty subsistence. While the demand for the labour and the price of provisions, therefore, remain the same, a direct tax upon the wages of labour can have no other effect, than to raise them somewhat higher than the tax. Let us suppose, for example, that, in a particular place, the demand for labour and the price of provisions were such as to render ten shillings a-week the ordinary wages of labour; and that a tax of one-fifth, or four shillings in the pound, was imposed upon wages. If the demand for labour and the price of provisions remained the same, it would still be necessary that the labourer should, in that place, earn such a subsistence as could be bought only for ten shillings a-week; so that, after paying the tax, he should have ten shillings a-week free wages. But, in order to leave him such free wages, after paying such a tax, the price of labour must, in that place, soon rise, not to twelve shillings a week only, but to twelve and sixpence; that is, in order to enable him to pay a tax of one-fifth, his wages must necessarily soon rise, not one-fifth part only, but one-fourth. Whatever was the proportion of the tax, the wages of labour must, in all cases rise, not only in that proportion, but in a higher proportion. If the tax for example, was one-tenth, the wages of labour must necessarily soon rise, not one-tenth part only, but oneeighth.
