The assumption is made in the laissez-faire doctrine that the interest of the public harmonizes with that of the individual. But this proves often not to be the case. For example, the forest has an immediate value to its owners and to the consumers of lumber, and it has also a diffused utility in its influence on industry, on climate, on navigation, on water-power and on floods. Yet, as the private owner, unless a great land monopolist, does not control enough of the forest to appreciably affect any of these things, and could rarely sell them even if he could affect them, he will cut down the tree whenever he can gain by doing so. In this situation either governmental control or governmental ownership of forests is essential.

Each kind of political unit, or subdivision of government, develops characteristic kinds of public ownership and industry. Federal states consist of three main groups of political units: national, provincial, and local. Provincial units are the largest subdivisions, as the American "states," or commonwealths, the German states, and the provinces in other countries. The term local political unit is more complex and may mean county, township, village, city, or school or sanitary district; but most of what is to be said of local ownership refers to cities or to incorporated villages.

§ 4. #Forms of municipal ownership#. Local political units acquire ownership only in local industries and in wealth used locally by the citizens. Nearly all parks and recreation grounds are owned by cities. As population has become more dense, private yards of any extent have become impossible, in cities, for all but the wealthy. Public ownership of parks insures a "breathing place" and recreation grounds to the common man in the most economical way. Of late the movement for large and small public parks and playgrounds has gone on rapidly in American cities. Related to parks are public baths, public libraries, art collections, museums, zoological gardens, etc. Some have seen danger in this policy, but the public sees no such danger so long as the things supplied gratify the higher tastes—as art, music, literature, and social recreation. These give no encouragement to the increase of improvident families and to the breaking down of independent character. The means of local communication—streets, roads, bridges—were once owned largely by private citizens. Here and there still are found toll roads and toll bridges built under charters granted a century ago, but tolls on public thoroughfares are for the most part abolished. A public market, where the producer from the farm and the city consumer can meet, is an old institution. About two thirds of the cities of 30,000 population or more have public markets or scales, and fully one third have public markets of importance. New York City has six large retail and wholesale markets, for selling meat and farm produce, in which rents or fees are charged, and several open markets. There has recently been a large movement in this direction.

The providing of apparatus for extinguishing fires is always a public duty; the conveyance of waste water is increasingly a public function. The supply of pure water for domestic and business uses, for fire protection and for street cleaning, while often a private enterprise in villages, and sometimes in large cities, is increasingly undertaken by public agencies. Most of the largest cities now own their own water supply systems. Public ownership of gas and electric lighting is less common, as the utility supplied is not so essential and the industry is somewhat less subject to monopoly; but the difference is one of degree only. Street railroads are often under public ownership in Europe; but there have thus far been few cases of the kind in the United States and Canada.[4]

§ 5. #Localized production favoring monopoly#. A number of these enterprises have characteristics in common which appear to make inevitable their drift into monopolistic control. Waterworks, gas, electric lighting, street railways, telephone systems, are among these. However fierce may be the competition for a time, sooner or later either one company drives out the other or buys it up, or both come to an agreement by which the public is made to pay higher prices.

A feature favoring the growth of monopoly when such industries are left to private enterprise is the need to produce and supply the commodity or service at a given locality. While two street railways can compete on neighboring streets, it is physically impossible for two or more to compete on the same street. Two systems of water-mains or gas-mains can be put down, as sometimes is done, but this is not only a great economic waste, but the tearing up of the streets is an intolerable public nuisance. This difficulty is less marked in the case of telephones and electric lighting, and some persons still cling to faith in competition to regulate the rates in those industries; but faith in competition between water companies and between gas companies has been given up by nearly all persons now, as it was long since by students of the subject.

§ 6. #Economies of large production favoring monopoly#. A second feature favoring monopoly in such industries is the marked advantage of large production in them. These industries are usually spoken of as "industries of increasing returns." This advantage is enjoyed in some degree by every enterprise, but it is gradually neutralized and limited. The need to extend an expensive physical plant to every point where customers are to be served, and the very much smaller cost per unit of delivering large amounts of water, gas, electricity, and transportation, on the same street, offers a greater inducement for one competitor to crowd out or buy out the other at a more than liberal price. Even then, larger net dividends and correspondingly larger capitalization are secured than were before possible to both companies combined.

§ 7. #Uniformity of products favoring monopoly#. A third feature favoring monopoly is uniformity in the quality of the furnished. It is a general truth that competition is most persistent where there is the greatest range of choice open to the customer, and consequently the most individual treatment required of the enterpriser. An artist, even a storekeeper, attracts about him a body of patrons who like his product (for the merchant's manner and method of dealing are a part of the quality of his goods), and who cannot be tempted away by slight differences in price. Rival companies in the stage of competition are seen to claim superiority for their particular goods and to improve their service in every way possible. A new telephone company, entering where a monopoly has held the field, works at once a wonderful betterment in rates, courtesy, and service. But as the product of all competitors attains the highest technical standard possible at the time, the rivalry is reduced to one of price, and it is usually a "fight to the finish."

§ 8. #Franchises favoring monopoly#. A fourth feature favoring monopoly in these enterprises is the necessity of making permanent and exceptional use of the public streets and alleys. If this right were granted by a general law to every citizen, this feature would be sufficiently implied in the foregoing discussion. As it would be intolerable to allow private interests to use public property in whatever way they wished, the legislative body makes special grants in such cases in view of the circumstances. Not only is the legislature (or council, or county board of commissioners, etc.) led by the economic difficulties to withhold a charter from a second company, but it may be corruptly influenced by the company already established. The knowledge of the opposition to be encountered in getting a franchise must keep competitors out, even tho monopoly prices are maintained.

In view of these several features, which are so closely related that they form a common character, more or less fully shared by various industries, and especially in view of the necessity for the formal granting to them of peculiar privileges in the form of a public franchise, the public, in order to protect the general interest, is forced to undertake an exceptional control of these industries.
