Each factory turns out products different from those of other plants. Each hotel has a monopoly on the sale of its services on the site of its premises. The professional services rendered by a physician or a lawyer are never perfectly equal to those rendered by any other physician or lawyer. Except for certain raw materials, foodstuffs, and other staple goods, monopoly is everywhere on the market.
However, the mere phenomenon of monopoly is without any significance and relevance for the operation of the market and the determination of prices. It does not give the monopolist any advantage in selling his products. Under copyright law every rhymester enjoys a monopoly in the sale of his poetry. But this does not influence the market. It may happen that no price whatever can be realized for his stuff and that his books can only be sold at their waste paper value.
One must not confuse the notions of monopoly and of monopoly prices. Mere monopoly as such is of no importance if it does not result in monopoly prices.
The publisher of a copyright book is a monopolist. But he may not be able to sell a single copy no matter how low the price he asks. Not every price at which a monopolist sells a monopolized commodity is a monopoly price. Monopoly prices are only prices at which it is more advantageous for the monopolist to restrict the total amount to be sold than to expand his sales to the limit which a competitive market would allow.
Monopoly prices are the outgrowth of government interference with business. They were not created by the interplay of the factors operating on a free market. They are not products of capitalism, but precisely of the endeavors to counteract the forces determining the height of market prices. It is a distortion of fact to speak of monopoly capitalism. It would be more appropriate to speak of monopoly interventionism or monopoly statism.
The important place that cartels occupy in our time is an outcome of the interventionist policies adopted by the governments of all countries. The monopoly problem mankind has to face today is not an outgrowth of the operation of the market economy. It is a product of purposive action on the part of governments. It is not one of the evils inherent in capitalism as the demagogues trumpet. It is, on the contrary, the fruit of policies hostile to capitalism and intent upon sabotaging and destroying its operation.
It is a grotesque distortion of the true state of affairs to speak of monopoly capitalism instead of monopoly interventionism and of private cartels instead of government-made cartels.
