An Inquiry Into the Nature and Causes of the Wealth of Nations

by Adam Smith; M. Garnier

In the plan of direct taxation, the impost appears without any disguise; it comes upon us unexpectedly, from the imprudence so common to the bulk of mankind, and never fails to carry with it constraint and discouragement.

All these considerations are overlooked by the friends of direct taxation; and yet their importance must be well known to all who have ever attended to the art of governing men.

But, perhaps, this is not all. An indirect tax, by increasing from time to time the price of the objects of general consumption, when the members of the community have contracted the habit of this consumption, renders these objects a little more costly, and thus gives birth to that increase of labour and industry which is now required to obtain them. But if this tax be so proportioned as not to discourage the consumption, will it not then operate as a universal stimulus upon the active and industrious part of the community? Will it not incite that part to redoubled efforts, by which it may still enjoy those luxuries which, by habit, have become almost necessaries, and, of course, produce a further developement of the productive powers of labour, and of the resources of industry? Are we not, in such a case, to conclude, that after the imposition of a tax, there will exist not only the quantity of labour and industry which was formerly requisite to procure the necessaries and habitual enjoyments of the active class of mankind, but also such an addition to this, as will suffice for the payment of the tax? And will not this tax, or increase of produce required for the tax—as it is spent by the government that receives it—will it not serve to support a new class of consumers, requiring a variety of commodities which the impost enables them to pay? If these conjectures are well founded, it will follow, that indirect taxation, far from having any hurtful influence on wealth and population, must, when wisely regulated, tend to increase and strengthen these two great foundations of national prosperity and power. And it will tend to do this, inasmuch as it bears immediately on the body of the people, and operates on the working and industrious class, which forms the active part of the community; while, on the other hand, direct taxation operates solely on the idle class of landed proprietors—which furnishes us with the characteristic difference existing between these two modes of taxation.[5] These hints, which seem to afford an explanation of that most extraordinary phenomenon in political economy, viz. the rapid and prodigious increase of wealth in those nations which are most loaded with indirect taxes, deserve to be discussed at greater length than our limits will allow. Enough, however, has been said to shew, that no rigorous and purely mathematical calculation will ever enable us to appreciate the real influence of taxes upon the prosperity of a nation. Thus, some of the truths perceived by the economists are of little use in practice; while others are found to be contradicted in their application, by those accessory circumstances which were overlooked in the calculations of the theory.

While this sect of philosophers filled all Europe with their speculations, an observer of more depth and ability directed his researches to the same subject, and laboured to establish, on a true and lasting foundation, the doctrines of political economy.

Dr. Smith succeeded in discovering a great truth,—the most fruitful in consequences, the most useful in practice, the origin of all the principles of the science, and one which unveiled to him all the mysteries of the growth and distribution of wealth. This great man perceived, that the universal agent in the creation of wealth is labour; and was thence led to analyse the powers of this agent, and to search after the causes to which they owe their origin and increase.

The great difference between the doctrine of Smith and of the economists, lies in the point from which they set out, in the reduction of their consequences. The latter go back to the soil as the primary source of all wealth; while the former regards labour as the universal agent which, in every case, produces it. It will appear, at first sight, how very superior the school of the Scotch professor is to that of the French philosophers, with regard to the practical utility, as well as to the application of its precepts. Labour is a power of which man is the machine; and, of course, the increase of this power can only be limited by the indefinite bounds of human intelligence and industry; and it possesses, like these faculties, a susceptibility of being directed by design, and perfected by the aid of study. The earth, on the contrary, if we set aside the influence which labour has over the nature and quantity of its productions, is totally out of our power, in every respect which can render it more or less useful—in its extent, in its situation, and in its physical properties.

Thus the science of political economy, considered according to the view of the French economists, must be classed with the natural sciences, which are purely speculative, and can have no other end than the knowledge of the laws which regulate the object of their researches; while, viewed according to the doctrine of Smith, political economy becomes connected with the other moral sciences, which tend to ameliorate the condition of their object, and to carry it to the highest perfection of which it is susceptible.

A few words will suffice to explain the grounds of the doctrine of Smith. The power by which a nation creates its wealth is its labour; and the quantity of wealth created will increase in direct proportion as the power increases. But the increase of this last may take place in two ways—in energy, and in extent. Labour increases in energy, when the same quantity of labour furnishes a more abundant product; and the two great means of effecting the increase, or of perfecting the productive powers of labour, are the division of labour, and the invention of such machines as shorten and facilitate the manual operations of industry. Labour increases in extent, when the number of those engaged in it augments in proportion to the increasing number of the consumers, which can take place only in consequence of an increase of capitals, and of those branches of business in which they are employed.

Now, to accomplish the increase of labour in both these ways, and to conduct it gradually to the utmost pitch of energy and extent to which it can reach in any nation, considering the situation, the nature, and the peculiarities of its territories, what are the exertions to be made by its government? The subdivision of labour, and the invention and perfecting of machines. These two great means of augmenting the energy of labour, advance in proportion to the extent of the market, or, in other words, in proportion to the number of exchanges which can be made, and to the ease and readiness with which these can take place. Let the government, then, direct all its attention to the enlargement of the market, by forming safe and convenient roads, by the circulation of sterling coin, and by securing the faithful fulfilment of contracts; all of which are indispensible measures, at the same time that, when put in practice, they will never fail to attain the desired end. And the nearer a government approaches to perfection in each of these three points, the more certainly will it produce every possible increase of the national market. The first of the three means is, without doubt, the most essential, as no other expedient whatever can possibly supply its place.

The gradual accumulation of capitals is a necessary consequence of the increased productive powers of labour, and it becomes also a cause of still farther increase in these powers; but, in proportion as this accumulation becomes greater and greater, it serves to increase the extent of labour, inasmuch as it multiplies the number of labourers, or the sum of national industry. This increase, however, of the number of hands in the nation employed, will always be regulated by the nature of the business to which the capitals are dedicated.
