Skilled Laborers are those, who have had to pass through something equivalent to an apprenticeship in order to be able to offer their services for sale. These, as a class, present some considerable points of difference from common laborers. Their numbers are fewer, for the reason, that relatively few parents can afford to give their children the time and money needful for them to learn a trade, or to become skilful in any art requiring prolonged education; as a result of this lessened press of competition among themselves, and because being intelligent and consequently mobile they are able to insist better on their claims and distribute themselves to points where their services are in more demand; and because they are likely to be subject to a stronger Demand than common laborers, on account of the close connection of their services with special accumulations of Capital; the Wages of skilled laborers will infallibly rule higher than those of common laborers. Artisans in general constitute this second class of laborers. Professional Laborers are those, who have received a technical education,--something more than an apprenticeship,--expressly to fit them to render difficult and delicate services to their fellow-men for pay, and who possess besides the requisite character and talents and genius to enable them to succeed. Clergymen, physicians, lawyers, literary men, artists, actors, and many more, render professional services loosely so-called. The obstacles at the entrance of this path occasioned by the lack (1) of appropriate natural gifts, or (2) of the requisite industry and character, or (3) of the means of suitable education and training, practically exclude so many persons, that the competition in the higher walks of professional life is not such as to prevent a very large remuneration for services rendered. The demand for these is often peculiarly intense, as well as the supply peculiarly limited. When great interests of property, of reputation, of life, are at stake, it is felt that the best men to secure these must be had at almost any price. Fees and rewards for services of great delicacy, of great difficulty, of great danger, are paid by individuals and corporations and nations without grudging. Comparatively few men reach the highest points of excellence in their respective professions, and they have in consequence a natural monopoly in these fields of effort, and receive for their labor a very high rate of Wages. For example, Daniel Webster often took a fee of $1000 for a single plea in court; Paganini, a like sum for an hour's playing on a violin; and Jenny Lind, at least as much for an evening's singing in a concert, because there was in each case a strong demand for a peculiar service and only one person in the world who could render that service in the circumstances to the same perfection. But the objections which lie with such force against artificial monopolies, cannot be urged at all against a natural monopoly; for, if
