CHAPTER II.

UTILITY.

#10. Our Wants are various.# After a little reflection, we shall see

that we generally want but little of any one kind of commodity, and

prefer to have a portion of one kind and a portion of another kind.

Nobody likes to make his dinner off potatoes only, or bread only, or

even beef only; he prefers to have some beef, some bread, some potatoes,

besides, perhaps, beer, pudding, &c. Similarly, a man would not care to

have many suits of clothes all alike; he may wish to have several suits,

no doubt, but then some should be warmer, others thinner; some for

evening dress, others for travelling, and so on. A library all made of

copies of the same book would be absurd; to keep several exact

duplicates of any work would be generally useless. A collector of

engravings would not care to have many identical copies of the same

engraving. In all these, and many other cases, we learn that _human

wants tend towards variety_; #each separate want is soon satisfied, or

made full# (Latin, _satis_, enough, and _facere_, to make), and then

some other want begins to be felt. This was called by Senior #the law of

variety#, and it is the most important law in the whole of political

economy.

It is easy to see, too, that there is a natural order in which our wants

follow each other as regards importance; we must have food to eat, and

if we cannot get anything else we are glad to get bread; next we want

meat, vegetables, fruit, and other delicacies. Clothing is not on the

whole as necessary as food; but, when a man has plenty to eat, he begins

to think of dressing himself well. Next comes the question of a house to

live in; a mere cabin is better than nothing, but the richer a man is

the larger the house he likes to have. When he has got a good house he

wants to fill it with furniture, books, pictures, musical instruments,

articles of vertu, and so forth. Thus we can lay down very roughly #a

law of succession of wants#, somewhat in this order: air, food,

clothing, lodging, literature, articles of adornment and amusement.

It is very important to observe that there is no end nor limit to the

number of various things which a rich man will like to have, if he can

get them. He who has got one good house begins to wish for another: he

likes to have one house in town, another in the country. Some dukes and

other very rich people have four, five, or more houses. From these

observations we learn that there can never be, among civilised nations,

so much wealth, that people would cease to wish for any more. However

much we manage to produce, there are still many other things which we

want to acquire. When people are well fed, they begin to want good

clothing; when they are well clothed, they want good houses, and

furniture, and objects of art. If, then, too much wealth were ever

produced, it would be #too much of one sort, not too much of all sorts#.

Farmers might be ruined if they grew so much corn that nobody could eat

it all; then, instead of producing so much corn, they ought to produce

more beef and milk. Thus there is no fear that, by machinery or other

improvements, things will be made so plentifully that workmen would be

thrown out of employment, and not wanted any more. If men were not

required at one trade, they would only need to learn a new trade.

#11. When things are useful.# The chief question to consider, then, is

when things are useful and when they are not. #This entirely depends

upon whether we want them or not.# Most things about us, the air, rain

water, stones, soil, &c., are not wealth, because we do not want them,

or want so little that we can readily get what we need. Let us consider

carefully whether we can say that #water is useful#, or in what sense we

may say so. It is common to hear people say that water is the most

useful substance in the world, and so it is--in the right place, and at

the right time. But if water is too plentiful and flows into your

cellars, it is not useful there; if it soaks through the walls and

produces rheumatism, it is hurtful, not useful. If a man wanting pure

good water, digs a well and the water comes, it is useful. But if, in

digging a coal pit, water rushes in and prevents the miners reaching the

coal seam, it is clear that the water is the opposite of useful. In some

countries rain comes very irregularly and uncertainly. In Australia the

droughts last for one or two or even three years, and in the interior of

the continent the rivers sometimes dry up altogether. The dirtiest pools

then become very valuable for keeping the flocks of sheep alive. In New

South Wales water has been sold for three shillings a bucketful. When a

drought breaks up, sudden floods come down the rivers, destroying the

dams and bridges, sweeping away houses, and often drowning men and

animals. It is quite plain that we cannot say water is always useful; it

is often so hurtful as to ruin and drown people. All that we can really

say is that #water is useful when and where we want it, and in such

quantity as we want, and not otherwise#. We must not say that all water

is useful, but only that such water is useful as we can actually use.

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.

We see, then, that it is simple folly to approve of consumption for its

own sake, or because it benefits trade. In spending our wealth we ought

to think solely of the advantage which people get out of that spending.

#15. The Fallacy of Non-consumption.# Some people fall into the opposite

fallacy of thinking that all spending is an evil. The best thing to do

with wealth is to keep it and let it grow by interest, or even to

neglect the interest and keep the gold itself. Thus they become what we

call misers, and there are always a certain number of people, who

deprive themselves of the ordinary pleasures of life, in order that they

may have the pleasure of feeling rich. Now these kind of people do no

positive harm to their fellow-men; on the contrary they increase the

wealth of the country, and some one or other will sooner or later

benefit by it. Moreover, if they put their wealth into banks and other

good investments, they do great service in increasing the capital of the

nation, and thus enabling so many more factories, docks, railways, and

other important works to be constructed. Most people are so fond of

spending their money on passing amusements, entertainments, eating and

drinking, and fine dressing, that it is a distinct advantage to have

other people who will put their wealth into a more permanently useful

form.

Nevertheless, there could be no use in abstaining from all enjoyment in

order that we might lay up a store of wealth. Things are not wealth

unless they are useful and pleasant to us. If everybody invested his

savings in railway shares, we should have so many railways that they

could not be all used, and they would become rather a nuisance than a

benefit. Similarly, there could be no good in building docks unless

there were ships to load in them, nor ships unless there were goods or

passengers to convey. It would be equally absurd to make cotton mills if

there were already enough to manufacture as much cotton goods as people

could consume.

Thus we come to see that wealth must be fitted for use and consumption

in some way or other. What we have to do is to endeavour to spend our

means so as to get the greatest real happiness for ourselves, our

relatives, friends, and all other people whom we ought to consider.
