Had this state continued, the wages of labour would have augmented with all those improvements in its productive powers, to which the division of labour gives occasion. All things would gradually have become cheaper. They would have been produced by a smaller quantity of labour; and as the commodities produced by equal quantities of labour would naturally in this state of things be exchanged for one another, they would have been purchased likewise with the produce of a smaller quantity. But though all things would have become cheaper in reality, in appearance many things might have become dearer, than before, or have been exchanged for a greater quantity of other goods. Let us suppose, for example, that in the greater part of employments the productive powers of labour had been improved to tenfold, or that a day’s labour could produce ten times the quantity of work which it had done originally; but that in a particular employment they had been improved only to double, or that a day’s labour could produce only twice the quantity of work which it had done before. In exchanging the produce of a day’s labour in the greater part of employments for that of a day’s labour in this particular one, ten times the original quantity of work in them would purchase only twice the original quantity in it. Any particular quantity in it, therefore, a pound weight, for example, would appear to be five times dearer than before. In reality, however, it would be twice as cheap. Though it required five times the quantity of other goods to purchase it, it would require only half the quantity of labour either to purchase or to produce it. The acquisition, therefore, would be twice as easy as before. But this original state of things, in which the labourer enjoyed the whole produce of his own labour, could not last beyond the first introduction of the appropriation of land and the accumulation of stock. It was at an end, therefore, long before the most considerable improvements were made in the productive powers of labour; and it would be to no purpose to trace further what might have been its effects upon the recompence or wages of labour. As soon as land becomes private property, the landlord demands a share of almost all the produce which the labourer can either raise or collect from it. His rent makes the first deduction from the produce of the labour which is employed upon land.
