Excerpt from An Inquiry into
the Nature and Causes of the Wealth of Nations
Published in 1776
"The division of labor, however, so far as it can be introduced, occasions, in every art, a proportionate increase of the productive powers of labour."
Adam Smith (1723–1790) was one of the first people to write about what is now called economics, the way a people in a society make a living and spend money. Smith was a professor at the University of Glasgow in 1776 when he published his most famous work, An Inquiry into the Nature and Causes of the Wealth of Nations, usually called simply The Wealth of Nations. His topic was how the British government could increase the wealth of the country by adopting certain policies and avoiding others. Smith believed in laissez-faire (pronounced less-say-FAIR, a French term meaning "free to do") economics, relying on the free market to proceed without government interference. His book has been studied ever since, both by government officials and by economists (people who study how people and nations make a living).
One of Smith's concerns was how to improve the productivity of labor. (Productivity is the measure of how much value a person creates in a period of time, such as a week or a year. Smith thought the best way to maximize productivity was to let individuals focus on specific tasks and become very good at doing just one or two things, a theory he called the division of labor. The notion that workers should specialize in a single task was later used in setting up assembly lines to make complex objects, like a car, by letting each worker do just one thing, such as attach the wheels.
This selection from The Wealth of Nations comes from the very beginning of the book. The example Smith uses to illustrate his point is people who manufacture pins (like those used in sewing). Smith says that if an individual were to try to do the whole job of making pins—from pulling a piece of wire into a very thin strand to putting the head on the pin—the result might be producing one pin a day. But if ten people divided the task into its separate parts, together they could produce about forty-eight thousand pins a day—or about forty-eight hundred pins per individual.
Smith's example describes the way new factories were being set up at the beginning of the Industrial Revolution, the term used to describe the introduction of new water- or steam-powered machines in factories to replace work traditionally done by hand. The Industrial Revolution was getting started at the same time Smith was writing. In the new factories, work was reorganized in the way Smith recommended, with an individual worker assigned part of the overall task. (In the older methods, workers at home were responsible for the whole process of spinning yarn or weaving cloth, for example.) Smith wrote that the division of labor was an important reason that Britain was becoming wealthier than nations where traditional methods were used.
Smith thought farming was an exception to the idea of division of labor. One farmer usually did a variety of jobs as one season moved to the next. And for that reason, he wrote, British farming did not have an advantage over any other country's farming, whereas British manufacturing (where division of labor was the rule) enjoyed a huge advantage.
Things to remember while reading the excerpt from The Wealth of Nations:
- Smith's book was published in 1776, at the beginning of the Industrial Revolution. He had not yet seen the eventual results of the division of labor—how monotonous and boring jobs could become, or how factory owners would insist that workers stay on the job for twelve or sixteen hours a day, long after they were exhausted.
- Smith was thinking about how to increase the wealth of Great Britain as a whole society. His study on the division of labor was not so concerned with how much workers should be paid, although he took up this subject later in his book.
- In England in the 1700s, working people had very few political rights, and there was not much concern for their welfare. On the other hand, people who owned property—both land, used for farming, and equipment or facto-ries—had a lot of rights. Smith was primarily concerned with how property owners should behave to increase the wealth of the country.
- Smith used the language and spelling of his time, which is preserved in this excerpt.
Excerpt from The Wealth of Nations
The greatest improvement in the productive powers of labour, and the greater part of the skill, dexterity, and judgment with which it is any where directed, or applied, seem to have been the effects of the division of labour.
The effects of the division of labour, in the general business of society, will be more easily understood, by considering in what manner it operates in some particular manufactures. It is commonly supposed to be carried furthest in some very trifling ones; not perhaps that it really is carried further in them than in others of more importance: but in those trifling manufactures which are destined to supply the small wants of but a small number of people, the whole number of workmen must necessarily be small; and those employed in every different branch of the work can often be collected into the same workhouse, and placed at once under the view of the spectator.
In those great manufactures, on the contrary, which are destined to supply the great wants of the great body of the people, every different branch of the work employs so great a number of workmen, that it is impossible to collect them all into the same workhouse. We can seldom see more, at one time, than those employed in one single branch. Though in such manufactures, therefore, the work may really be divided into a much greater number of parts, than in those of a more trifling nature, the division is not near so obvious, and has accordingly been much less observed.
To take an example, therefore, from a very trifling manufacture; but one in which the division of labour has been very often taken notice of, the trade of the pin-maker; a workman not educated to this business (which the division of labour has rendered a distinct trade), nor acquainted with the use of the machinery employed in it (to the invention of which the same division of labour has probably given occasion), could scarce, perhaps, with his utmost industry, make one pin in a day, and certainly could not make twenty. But in the way in which this business is now carried on, not only the whole work is a peculiar trade, but it is divided into a number of branches, of which the greater part are likewise peculiar trades. One man draws out the wire, another straights it, a third cuts it, a fourth points it, a fifth grinds it at the top for receiving the head; to make the head requires two or three distinct operations; to put it on, is a peculiar business, to whiten the pins is another; it is even a trade by itself to put them into the paper; and the important business of making a pin is, in this manner, divided into about eighteen distinct operations, which, in some manufactories, are all performed by distinct hands, though in others the same man will sometimes perform two or three of them. I have seen a small manufactory of this kind where ten men only were employed, and where some of them consequently performed two or three distinct operations. But though they were very poor, and therefore but indifferently accommodated with the necessary machinery, they could, when they exerted themselves, make among them about twelve pounds of pins in a day. There are in a pound upwards of four thousand pins of a middling size. Those ten persons, therefore, could make among them upwards of forty-eight thousand pins in a day. Each person, therefore, making a tenth part of forty-eight thousand pins, might be considered as making four thousand eight hundred pins in a day. But if they had all wrought separately and independently, and without any of them having been educated to this peculiar business, they certainly could not each of them have made twenty, perhaps not one pin in a day; that is certainly, not the two hundred and fortieth, perhaps not the four thousand eight hundredth part of what they are at present capable of performing, in consequence of a proper division and combination of their different operations.
In every other art and manufacture, the effects of the division of labour are similar to what they are in this very trifling one; though, in many of them, the labour can neither be so much subdivided, nor reduced to so great a simplicity of operation. The division of labour, however, so far as it can be introduced, occasions, in every art, a proportionate increase of the productive powers of labour. The separation of different trades and employments from one another, seems to have taken place, in consequence of this advantage. This separation too is generally carried furthest in those countries which enjoy the highest degree of industry and improvement; what is the work of one man in a rude state of society, being generally that of several in an improved one. In every improved society, the farmer is generally nothing but a farmer; the manufacturer, nothing but a manufacturer. The labour too which is necessary to produce any one complete manufacture, is almost always divided among a great number of hands. How many different trades are employed in each branch of the linen and woollen manufacturers, from the growers of the flax and the wool, to the bleachers and smoothers of the linen, or to the dyers and dressers of the cloth! The nature of agriculture, indeed, does not admit of so many subdivisions of labour, nor of so complete a separation of one business from another, as manufactures. It is impossible to separate so entirely, the business of the grazier from that of the corn-farmer, as the trade of carpenter is commonly separated from that of the smith. The spinner is almost always a distinct person from the weaver; but the ploughman, the harrower, the sower of the seed, and the reaper of the corn, are often the same. The occasions for those different sorts of labour returning with the different seasons of the year, it is impossible that one man should be constantly employed in any one of them. This impossibility of making so complete and entire a separation of all the different branches of labour employed in agriculture, is perhaps the reason why the improvement of the productive powers of labour in this art, does not always keep pace with their improvement in manufactures. The most opulent nations, indeed, generally excel all their neighbours in agriculture as well as in manufacturers; but they are commonly more distinguished by their superiority in the latter than in the former. Their lands are in general better cultivated, and having more labour and expence bestowed upon them, produce more in proportion to the extent and natural fertility of the ground. But this superiority of produce is seldom much more than in proportion to the superiority of labour and expence. In agriculture, the labour of the rich country is not always much more productive than that of the poor; or, at least, it is never so much more productive, as it commonly is in manufactures. The corn of the rich country, therefore, will not always, in the same degree of goodness, come cheaper to market than that of the poor. The corn of Poland, in the same degree of goodness, is as cheap as that of France, notwithstanding the superior opulence and improvement of the latter country. The corn of France is, in the corn provinces, fully as good, and in most years nearly about the same price with the corn of England, though, in opulence and improvement, France is perhaps inferior to England. The corn-lands of England, however, are better cultivated than those of France, and the corn-lands of France are said to be much better cultivated than those of Poland. But though the poor country, notwithstanding the inferiority of its cultivation, can, in some measure, rival the rich in the cheapness and goodness of its corn, it can pretend to no such competition in its manufactures; at least if those manufactures suit the soil, climate, and situation of the rich country. The silks of France are better and cheaper than those of England, because the silk manufacture, at least under the present high duties upon the importation of raw silk, does not so well suit the climate of England as that of France. But the hard-ware and the coarse woollens of England are beyond all comparison superior to those of France, and much cheaper too in the same degree of goodness. In Poland there are said to be scarce any manufactures of any kind, a few of those coarser household manufactures excepted, without which no country can well subsist.
This great increase of the quantity of work, which, in consequence of the division of labour, the same number of people are capable of performing, is owing to three different circumstances; first, to the increase of dexterity in every particular workman; secondly, to the saving of the time which is commonly lost in passing from one species of work to another; and lastly, to the invention of a great number of machines which facilitate and abridge labour, and enable one man to do the work of many.
First, the improvement of the dexterity of the workman necessarily increases the quantity of the work he can perform; and the division of labour, by reducing every man's business to some one simple operation, and by making this operation the sole employment of his life, necessarily increases very much the dexterity of the workman. A common smith, who, though accustomed to handle the hammer, has never been used to make nails, if upon some particular occasion he is obliged to attempt it, will scarce, I am assured, be able to make above two or three hundred nails in a day, and those too very bad ones. A smith who has been accustomed to make nails, but whose sole or principal business has not been that of a nailer, can seldom with his utmost diligence make more than eight hundred or a thousand nails in a day. I have seen several boys under twenty years of age who had never exercised any other trade but that of making nails, and who, when they exerted themselves, could make, each of them, upwards of two thousand three hundred nails in a day. The making of a nail, however, is by no means one of the simplest operations. The same person blows the bellows, stirs or mends the fire as there is occasion, heats the iron, and forges every part of the nail: In forging the head too he is obliged to change his tools. The different operations into which the making of a pin, or of a metal button, is subdivided, are all of them much more simple, and the dexterity of the person, of whose life it has been the sole business to perform them, is usually much greater. The rapidity with which some of the operations of those manufactures are performed, exceeds what the human hand could, by those who had never seen them, be supposed capable of acquiring.
Secondly, the advantage which is gained by saving the time commonly lost in passing from one sort of work to another, is much greater than we should at first view be apt to imagine it. It is impossible to pass very quickly from one kind of work to another, that is carried on in a different place, and with quite different tools. A country weaver, who cultivates a small farm, must lose a good deal of time in passing from his loom to the field, and from the field to his loom. When the two trades can be carried on in the same work-house, the loss of time is no doubt much less. It is even in this case, however, very considerable. A man commonly saunters a little in turning his hand from one sort of employment to another. When he first begins the new work he is seldom very keen and hearty; his mind, as they say, does not go to it, and for some time he rather trifles than applies to good purpose. The habit of sauntering and of indolent careless application, which is naturally, or rather necessarily acquired by every country workman who is obliged to change his work and his tools every half hour, and to apply his hand in twenty different ways almost every day of his life; renders him almost always slothful and lazy, and incapable of any vigorous application even on the most pressing occasions. Independent, therefore, of his deficiency in point of dexterity, this cause alone must always reduce considerably the quantity of work which he is capable of performing.
Thirdly, and lastly, every body must be sensible how much labour is facilitated and abridged by the application of proper machinery. It is unnecessary to give any example. I shall only observe, therefore, that the invention of all those machines by which labour is so much facilitated and abridged, seems to have been originally owing to the division of labour. Men are much more likely to discover easier and readier methods of attaining any object, when the whole attention of their minds is directed towards that single object, than when it is dissipated among a great variety of things. But in consequence of the division of labour, the whole of every man's attention comes naturally to be directed towards some one very simple object. It is naturally to be expected, therefore, that some one or other of those who are employed in each particular branch of labour should soon find out easier and readier methods of performing their own particular work, wherever the nature of it admits of such improvement. A great part of the machines made use of in those manufactures in which labour is most subdivided, were originally the inventions of common workmen, who, being each of them employed in some very simple operation, naturally turned their thoughts towards finding out easier and readier methods of performing it. Whoever has been much accustomed to visit such manufacturers, must frequently have been shewn very pretty machines, which were the inventions of such workmen, in order to facilitate and quicken their own particular part of the work. In the first fire-engines, a boy was constantly employed to open and shut alternately the communication between the boiler and the cylinder, according as the piston either ascended or descended. One of those boys, who loved to play with his companions, observed that, by tying a string from the handle of the valve which opened this communication to another part of the machine, the valve would open and shut without his assistance, and leave him at liberty to divert himself with his play-fellows. One of the greatest improvements that has been made upon this machine, since it was first invented, was in this manner the discovery of a boy who wanted to save his own labour.
What happened next …
Adam Smith's ideas were already being widely adopted when he wrote his book. These practices became increasingly widespread, and Smith was quoted (and still is quoted) as an authority on the best way to organize manufacturing.
Smith died in 1790. Efforts by factory owners to speed up production, and to keep down the cost of hiring workers, led to horrific abuses in the early 1800s. Workers—including children—were required to be on the job for twelve or more hours a day, with few breaks. Exhaustion, and the monotony of doing the same task repeatedly, led to accidents that caused serious injury or even death.
Adam Smith did not live to observe the nature of factories in the 1800s; the abuses there resulted in laws and regulations passed by the British Parliament to protect children, women, and other workers. Would he still have believed in laissez-faire had he seen these conditions?
Did you know …
Adam Smith was an acquaintance of James Watt, the man who perfected the steam engine, which was central to the Industrial Revolution. Smith and Watt belonged to a group of individuals who called themselves the Lunar Society of Birmingham—or, sometimes, the Lunaticks—because they met for dinner on nights when the moon was full so that they could see their way home by the moonlight. Their club, which included a dozen other members, met almost every month for more than thirty years.
