and says, "that a man must be rich or poor according to the quantity of labour which he can afford to purchase." Now this description differs essentially from the other, and is certainly incorrect; for suppose the mines were to become more productive, so that gold and silver fell in value, from the greater facility of their production; or that velvets were to be manufactured with so much less labour than before, that they fell to half their former value; the riches of all those who purchased those commodities would be increased: one man might increase the quantity of his plate, another might buy double the quantity of velvet; but with the possession of this additional plate, and velvet, they could employ no more labour than before; because as the exchangeable value of velvet and of plate would be lowered, they must part with proportionally more of these species of riches to purchase a day's labour. Riches then cannot be estimated by the quantity of labour which they can purchase.
From what has been said, it will be seen that the wealth of a country may be increased in two ways: it may be increased by employing a greater portion of revenue in the maintenance of productive labour,—which will not only add to the quantity, but to the value of the mass of commodities; or it may be increased, without employing any additional quantity of labour, by making the same quantity more productive,—which will add to the abundance, but not to the value of commodities.
In the first case, a country would not only become rich, but the value of its riches would increase. It would become rich by parsimony; by diminishing its expenditure on objects of luxury and enjoyment; and employing those savings in reproduction.
In the second case, there will not necessarily be either any diminished expenditure on luxuries and enjoyments, or any increased quantity of productive labour employed, but with the same labour more would be produced; wealth would increase, but not value. Of these two modes of
