Quantity of labour is originally the only rule of value,
allowance being made for superior hardship,
and for uncommon dexterity and ingenuity.
The whole produce then belongs to the labourer,
but when stock is used, something must be given for the profits of the undertaker, and the value of work resolves itself into wages and profits.
Profits are not merely wages of inspection and direction.
The labourer shares with the employer, and labour alone no longer regulates value.
When land has all become private property, rent constitutes a third component part of the price of most commodities.
The real value of all three parts is measured by labour.
In an improved society all three parts are generally present,
for example, in corn,
in flour or meal,
and in flax.
Rent is a smaller proportion in highly manufactured commodities.
A few commodities have only two or even one of the three component parts.
But all must have at least one,
and the price of the whole annual produce resolves itself into wages, profits and rent,
which are the only original kinds of revenue.
They are sometimes confounded,
for example, a gentleman farmer’s rent is called profit,
a common farmer’s wages are called profit,
and so are an independent manufacturer’s wages,
while the rent and profit of a gardener cultivating his own land are considered earnings of labour.
A great part of the annual produce goes to the idle; the proportion regulates the increase or diminution of the produce.
