The labour created by luxuries, though useful in distributing the produce of the country, without vitiating the proprietor by power, or debasing the labourer by dependence, has not, indeed, the same beneficial effects on the state of the poor. A great accession of work from manufacturers, though it may raise the price of labour even more than an increasing demand for agricultural labour, yet, as in this case the quantity of food in the country may not be proportionably increasing, the advantage to the poor will be but temporary, as the price of provisions must necessarily rise in proportion to the price of labour. Relative to this subject, I cannot avoid venturing a few remarks on a part of Dr Adam Smith's Wealth of Nations, speaking at the same time with that diffidence which I ought certainly to feel in differing from a person so justly celebrated in the political world. CHAPTER 16 Probable error of Dr Adam Smith in representing every increase of the revenue or stock of a society as an increase in the funds for the maintenance of labour--Instances where an increase of wealth can have no tendency to better the condition of the labouring poor--England has increased in riches without a proportional increase in the funds for the maintenance of labour--The state of the poor in China would not be improved by an increase of wealth from manufactures. The professed object of Dr Adam Smith's inquiry is the nature and causes of the wealth of nations. There is another inquiry, however, perhaps still more interesting, which he occasionally mixes with it; I mean an inquiry into the causes which affect the happiness of nations or the happiness and comfort of the lower orders of society, which is the most numerous class in every nation. I am sufficiency aware of the near connection of these two subjects, and that the causes which tend to increase the wealth of a state tend also, generally speaking, to increase the happiness of the lower classes of the people. But perhaps Dr Adam Smith has considered these two inquiries as still more nearly connected than they really are; at least, he has not stopped to take notice of those instances where the wealth of a society may increase (according to his definition of 'wealth') without having any tendency to increase the comforts of the labouring part of it. I do not mean to enter into a philosophical discussion of what constitutes the proper happiness of man, but shall merely consider two universally acknowledged ingredients, health, and the command of the necessaries and conveniences of life.
