Note 21 — Of the Streets of London. (continued 4)

The usual argument in favour of machinery, viz., that “by reducing prices it extends the market, and so, causing a greater demand for the commodities, induces a greater quantity of employment,” would also be an argument in favour of over population, since this, by cheapening labour, must have the same effect as machinery on prices, and, consequently (according to the above logic), induce a greater quantity of employment! But granting that machinery really does benefit the labourer in cases where the market, and therefore the quantity of work, is largely extensible, surely it cannot but be an injury in those callings where the quantity of work is fixed. Such is the fact with the sawing of wood, the reaping of corn, the threshing of corn, the sweeping of the streets, &c., and hence the evil of mechanical labour applied to such trades.
