Some occupations are very badly paid, because they can be taken up by men who fail in other work. Frequently a person who has learnt a trade or profession finds that he is unfit for it; in other cases, there is a failure in the demand for a commodity, which obliges its manufacturers to seek other work. Such people are usually too old and too poor to begin again from the beginning, and learn a new difficult trade. Thus they have to take to the first work they can do. Educated men who have not been successful become secretaries, house-agents, insurance-agents, small wine merchants, and the like. Uneducated men have to drive cabs, or go into the army, or break stones; poor women become seamstresses, or go out charing. Here again we see the need of leaving everybody at perfect liberty to enter any trade which he can manage to carry on; it is not only injurious to the public, but it is most unfair to people in misfortune, if they are shut out of employments by the artificial restrictions of those who already carry on those employments. #46. What is a Fair Day's Wages?# It is a favourite saying that #a man should have a fair day's wages for a fair day's work; but this is a fallacious saying#. Nothing, at first sight, can seem more reasonable and just; but when you examine its meaning, you soon find that there is no real meaning at all. It amounts merely to saying, that #a man ought to have what he ought to have#. There is no way of deciding what is a fair day's wages. Some workmen receive only a shilling a day; others two, three, four, or five shillings; a few receive as much as ten, or even twenty shillings a day; which of these rates is fair? If the saying means that all should receive the _same_ fair wages, then all the different characters and powers of men would first have to be made the same, and exactly equalised. We have seen that wages vary according to the laws of supply and demand, and as long as workmen differ in skill, and strength, and the kind of goods they can produce, there must be differences of demand for their products. Accordingly, there is no more a fair rate of wages than there is a fair price of cotton or iron. It is all a matter of bargain; he who has corn or cotton or iron or any other goods in his possession, does quite right in selling it for the best price he can get, provided he does not prevent other people from selling their goods as they think best. So, any workman does quite right in selling his labour for the highest rate of wages he can get, provided that he does not interfere with the similar right of other workmen to sell their labour as they like.
