Political economy

by William Stanley Jevons

It is now easy to see why things, in order to be wealth, must be limited in supply; for we never want an unlimited quantity of anything. A man cannot drink more than two or three quarts of water in the day, nor eat more than a few pounds of food. Thus we can understand why in South America, where there are great herds of cattle, the best beef is not wealth, namely, because there is so much that there are not people enough to eat it. The beef which is eaten there is just as useful in nourishing people as beef eaten in England, but it is not so valuable because there is plenty of beef to spare, that is, plenty of beef not wanted by the people.

12. What we must aim at. Now we can see precisely what it is that we have to learn in political economy. It is how to supply our various wants as fully as possible. To do this we must, first of all, ascertain what things are wanted. There is no use making things unless, when made, they are useful, and the quantities of things must be proportioned to what are wanted. The cabinetmaker must not make a great many tables, and few chairs; he must make some tables and more chairs. Similarly, every kind of commodity must be supplied when it is most wanted; and nothing must be over-supplied, that is manufactured in such large quantities that it would have been better to spend the labour in manufacturing other things.

Secondly, we must always try to produce things with the least possible labour; for labour is painful exertion, and we wish to undergo as little pain and trouble as we can. Thus, as Professor Hearn, of the University of Melbourne, well described it, political economy is the science of efforts to satisfy wants; it teaches us how to find the shortest way to what we wish for. The object which we aim at is to obtain the most riches at the cost of the least labour.

13. When to consume wealth. To consume a commodity is to destroy its utility, as when coal is burnt, or bread eaten, or a jug broken, or a piano worn out. Things lose their utility in various ways, as when they go bad, like meat and fish; when the fashion changes, as with ladies' attire; or when they merely grow old, as in the case of an almanack, or a directory. Again, houses fall into bad repair; ricks of corn may be burnt down; ships may founder. In all these cases utility is destroyed, slowly or quickly, and the commodities may be said to be consumed. It is obvious that we must use things while they are fit to be used, if we are to use them at all.

It is evident, too, that we ought to try to get the utmost possible use out of things which we are happy enough to possess. If an object is not injured nor destroyed by use, as in the case of reading a book, or looking at a picture, then the more often we use it the greater is the utility. Such things become more useful if they are passed on from one person to another, like books in a circulating library. In this case there arises what we may call the multiplication of utility. Public libraries, museums, picture galleries and like institutions all multiply utility, and the cost of such institutions is little or nothing compared with their usefulness.

When a commodity is destroyed at once by use, as in the case of food, it is obvious that only one person can use the same portion of commodity. Our object must then be to consume it when it is most useful. If a man lost in the bush find himself with a short supply of food, it would be foolish of him to eat it all up at once, when he might starve for several days afterwards. He should spread out his supply, so as to eat each bit of food when it will support his strength the most. So we ought to do with the earnings of a life time. The working man should not spend all his wages when trade is brisk, because he will want some of it much more when trade becomes slack, and he is out of employment. Similarly, that which is spent in early life upon mere luxuries and frivolities, might be much more useful in old age, when even necessaries and ordinary comforts may be difficult to obtain. All wealth is produced in order that it may be consumed, but then it must be consumed when it best fulfils its purpose; that is, when it is most useful.

14. The Fallacy of Consumption. It is not uncommon to hear people say that they ought to spend money freely in order to encourage trade. If every person were to save his money instead of spending it, trade, they think, would languish and workmen would be out of employment. Tradespeople favour these notions, because it is obvious that, the more a milliner or draper can persuade his customer to buy, the more profit he makes thereby. The customers, too, are quite inclined to think the argument a good one, because they enjoy buying new dresses, and other pleasant things. Nevertheless the argument is a bad fallacy.

The fact is, that a person who has riches cannot help employing labour of some kind or other. If he saves up his money he probably puts it into a bank; but the banker does not keep it idle. The banker lends it out again to merchants, manufacturers and builders, who use it to increase their business and employ more hands. If he buy railway shares or government funds, those who receive the money put it to some other profitable use. If the rich man actually hoards up his money in the form of gold or silver, he gets no advantage from it, but he creates so much more demand for gold or silver. If many rich people were to take to hoarding up gold, the result would be to make gold mining more profitable, and there would be so many more gold miners, instead of railway navvies, or other workmen.

We see then that, when a rich person decides how to spend his money he is deciding not how many more workpeople shall be set to work, but what kind of work they shall do. If he decide to give a grand fancy ball, then in the end there will be so many more milliners, costumiers, lacemakers, confectioners, &c. A single ball indeed will have no great effect; but, if many people were to do the same, there would soon be more tradespeople attracted to these trades. If, on the other hand, rich people invest their money in a new railway, there will be so many more surveyors, engineers, foremen, navvies, iron puddlers, iron rollers, engine mechanics, carriage builders, &c.

The question really comes to this, whether people are made happier by more fancy balls, or by more railways. A fancy ball creates amusement at the time, but it costs a great deal of money, especially to the guests who buy expensive costumes. When it is over there is no permanent result, and no one is much the better for it. The railway, on the other hand, is no immediate cause of pleasure, but it cheapens goods by enabling them to be carried more easily: it allows people to live in the country, instead of the crowded town, or it carries them on pleasant and wholesome excursions.
