Child labor laws are a clear-cut example of restrictions placed on the employment of some labor for the benefit of restrictive wage rates for the remaining workers. In an era of much discussion about the “unemployment problem,” many of those who worry about unemployment also advocate child labor laws, which coercively prevent the employment of a whole body of workers. Child labor laws, then, amount to compulsory unemployment.

Laborers may also ask for geographical grants of oligopoly in the form of immigration restrictions. In the free market the inexorable trend is to equalize wage rates for the same value-productive work all over the earth. This trend is dependent on two modes of adjustment: businesses flocking from high-wage to low-wage areas, and workers flowing from low-wage to high-wage areas. Immigration restrictions are an attempt to gain restrictionist wage rates for the inhabitants of an area.

Tariffs and various forms of import quotas prohibit, partially or totally, geographical competition for various products. Domestic firms are granted a quasi monopoly and, generally, a monopoly price. Tariffs injure the consumers within the “protected” area, who are prevented from purchasing from more efficient competitors at a lower price. They also injure the more efficient foreign firms and the consumers of all areas, who are deprived of the advantages of geographic specialization.

One of the favorite arguments for licensing laws and other types of quality standards is that governments must “protect” consumers by insuring that workers and businesses sell goods and services of the highest quality. The answer, of course, is that “quality” is a highly elastic and relative term and is decided by the consumers in their free actions in the marketplace. The consumers decide according to their own tastes and interests, and particularly according to the price they wish to pay for the service.

Little attention has been paid to licenses; yet they constitute one of the most important (and steadily growing) monopolistic impositions in the current American economy. Licenses deliberately restrict the supply of labor and of firms in the licensed occupations. Various rules and requirements are imposed for work in the occupation or for entry into a certain line of business. Those who cannot qualify under the rules are prevented from entry. Further, those who cannot meet the price of the license are barred from entry.

Compulsory cartels are a forcing of all producers in an industry into one organization, or virtual organization. Instead of being directly barred from an industry, firms are forced to obey governmentally imposed quotas of maximum output. Such cartels invariably go hand in hand with a governmentally imposed program of minimum price control. When the government comes to realize that minimum price control by itself will lead to unsold surpluses and distress in the industry, it imposes quota restrictions on the output of producers.

Instead of making the product prohibition absolute, the government may prohibit production and sale except by a certain firm or firms. These firms are then specially privileged by the government to engage in a line of production, and therefore this type of prohibition is a grant of special privilege. If the grant is to one person or firm, it is a monopoly grant; if to several persons or firms, it is a quasi-monopoly or oligopoly grant. Both types of grant may be called monopolistic.

Another form of triangular intervention is interference with the nature of production directly, rather than with the terms of exchange. This occurs when the government prohibits any production or sale of a certain product. The consequence is injury to all parties concerned: to the consumers, who lose utility because they cannot purchase the product and satisfy their most urgent wants; and to the producers, who are prevented from earning a higher remuneration in this field and must therefore be content with lower earnings elsewhere.
