The monotony of labor, however, is to some extent a matter of temperament. Some workers find even routine tasks interesting because they are constantly trying to attain greater expertness at the particular job. Others find work of a very varied character to be monotonous. Footnote 14: There are two other forms of productive organization, neither of them very common. One is the co-operative association, with or without capital stock; the other is the organization of production under the direct management of the public authorities. The organization of the postal service is an example. Footnote 15: The Lockwood Committee, which made its investigations during 1920 in New York, found that excessive costs of building construction were due in considerable measure to the existence of artificial monopolies among producers of building materials. Footnote 16: It has been suggested that instead of giving inventors the exclusive right to make and sell their appliances, this right should be given to everybody with a provision that a fixed rate of royalty should be paid to the inventor. This would afford an incentive to the inventor while preventing the creation of legal monopolies. Footnote 17: The doctrine of the divine right of rulers was based upon certain Biblical texts, particularly Romans xiii, 1-7, and was put forth in the Middle Ages to support the secular rulers against the Church. The Bourbon kings of France, especially Louis XIV, asserted it, as well as the Stuart kings of England. The House of Hohenzollern in Germany maintained the doctrine, and the former Kaiser on more than one occasion alluded to himself as a ruler by divine right. Those who are interested in pursuing this topic further will find a great deal about it in J. N. Figgis, _The Divine Right of Kings_ (London, 1896) and in _The Political Writings of James I_ (ed. C. H. McIlwain, Cambridge, 1915). Footnote 18: For example, E. L. Godkin, _Unforeseen Tendencies of Democracy_ (N. Y., 1898), p. 46; Emile Faguet, _The Cult of Incompetence_ (N. Y., 1911), pp. 35-36; A. M. Kales, _Unpopular Government in the United States_ (Chicago, 1914); A. B. Cruikshank, _Popular Misgovernment in the United States_ (N. Y., 1920), and Alleyne Ireland, _Democracy and the Human Equation_ (N. Y., 1921), pp. 75-79. Footnote 19: Corporations, as well as individuals, are citizens in the eyes of the law. The Standard Oil Company of New Jersey is a citizen of New Jersey and as such is entitled to all the “privileges and immunities of citizens of the United States”. Footnote 20:
