(1.) #The Agreeableness or Disagreeableness of the Employments themselves.# If an employment is in itself comparatively pleasant, it attracts many who would not otherwise go into it at the current wages. Thus, officers of the army and navy are not on the average highly paid; but there is never any difficulty in finding men willing to be officers, because the work is thought to be easy, and there is honour and power attaching to it. On the other hand, a good butcher makes high wages, because his business is a greasy one, besides being thought to be cruel, and a clever man must be attracted to it by good earnings.
(2.) #The Easiness and Cheapness, or the Difficulty and Expense of learning the Occupation.# This circumstance always has much importance, because the greater number of the people are poor, and are consequently unable to give their children a long good education. Thus, the larger part of the young men who grow up are only fit for common manual employments, and therefore get low wages. To learn a profession, like that of an architect or engineer, it is requisite to pay a high premium, and become a pupil in a good office, and then there are many years to be spent in practising and waiting before profit begins to be made. Hence the comparatively few who succeed in the difficult professions gain very high wages.
(3.) #The Constancy or Inconstancy of Employment.# When a man is sure of being employed and paid regularly all the year round, he is usually willing on that account to accept a less rate of wages. Thus, there is little difficulty in finding men to be policemen at about 25 shillings a week; for though they have to go on duty at night, and their work is often tedious and disagreeable, yet policemen are nearly sure to have employment as long as they behave well. A carpenter or bricklayer, on the contrary, is sometimes thrown out of work, and becomes anxious as to the means of keeping his family. Masons and bricklayers, who cannot work during frosty weather, ought of course to have higher wages during the rest of the year, so as to make up a good average. Dock-labourers, who are simply strong men without any particular skill, earn large wages when trade is brisk and many ships come into the docks; at other times, when trade is slack, or when contrary winds keep ships out of port, they often fall into destitution through want of employment.
