It is true that from the very outset Adam Smith relates the notion of wealth to that of labour: The annual labour of every nation is the fund which originally supplies it with all the necessaries and conveniences of life which it annually consumes, and which consist always either in the immediate produce of that labour, or in what is purchased with that produce from other nations; it is also true that Smith relates the 'value in use' of things to men's needs, and their 'value in exchange' to the quantity of labour applied to its production: The value of any commodity, therefore, to the person who possesses it, and who means not to use or consume it himself, but to exchange it for other commodities, is equal to the quantity of labour which it enables him to purchase or command.
