The first important means to secure this which the author would suggest is simply an extension of the common-law principle of non-discrimination. A man in conducting certain sorts of business is permitted to do as he chooses. He may sell to one person and refuse to sell to another; he may give to one and withhold from another. But if he enters business as the keeper of an inn or as a common carrier of passengers or freight, he can no longer exercise partiality. He has elected to become a necessary servant of the public, and as such he is bound to serve impartially all who apply. In the same way a manufacturer while he engages in business under the usual laws of competition, may sell to whom he pleases and exercise such preference as he chooses. But when he combines with all other manufacturers of the same sort in a combination to restrict competition, he and his allies voluntarily change their relation to the public. Is it not true that they do actually elect to become necessary servants of the public—far more necessary, indeed, than the inn-keeper or the stage-coach driver,—and ought they not therefore to be placed under similar legal restrictions?

In every case where combination or consolidation restricts competition in an industry, one effect produced is an increase in the power over the public which the industry possesses. But this increased power over the public, thus voluntarily assumed, must inevitably carry with it increased responsibility to the public. It is the duty of the government to see that this responsibility is legally enforced.

This first principle, then, should be embodied in a law providing, in substance, that every person or firm entering into a contract to restrict competition should, so long as that contract was in force, be debarred from showing any preference in his or its purchases and sales, by giving more or less favorable prices to any person or firm than those quoted to any other person or firm. To enforce this requirement and prevent its evasion it is necessary to provide also that prices shall be public and that they shall not be altered without due notice. The requirement of publicity might be best effected by providing that the contract restricting competition should contain a schedule of prices, which would usually be the case in any event.

While this may seem like quite an assumption of authority on the part of the State, it is exactly what trusts and trade associations are striving to effect, though with the important qualification that when occasion, in the shape of an obnoxious competitor, requires, they wish to be at liberty to put prices up or down at short notice and exercise their preferences as they choose.

Let us now see what we would effect by the enforcement of this principle of non-discrimination. We have explained in the chapter on combinations in trade how one monopoly gains strength by alliance with another; as when the firms belonging to the car-spring combination made a contract with the steel combination by which that monopoly agreed to sell to them at a reduced price and to make an extra rate to their competitors. Under this law it would be impossible to found one monopoly upon the favors of another in this manner.

The obnoxious trade boycott, too, which is now becoming so common, would be effectually checked. And the scheme for crushing out a rival by giving all his customers specially favorable rates would no longer be practicable. The fact is that if we can stop the discriminations which the monopolies have practised, we shall cure a large share of the evils they have caused. It may be said that the courts will already punish many conspiracies of this sort; but a monopoly which is already breaking the law by its contracts of combination, finds in its methods of doing business plenty of chances to evade the laws against conspiracy. Certainly with a properly drawn law with reference to the publicity and stability of prices, it should be possible to practically wipe out the evil of discrimination by monopolies. It is also to be noted that the requirement of non-discrimination and of public and stable prices would bring profit in doing away with the waste of competition.

We have now to inquire what means it is possible to take to ensure that the prices charged by the monopoly shall not only be the same to all, but that they shall not in themselves be so exorbitant that the monopoly will reap large profits at the public expense. How can we keep the prices charged by the monopoly from rising far above the point where they would stand if free competition were in force? Two methods are open to us. We may keep down the monopoly's rates by what we will call potential competition, or we may reduce them directly by legislative enactment.

The right of the public to take this latter course may be defended on the ground that the monopoly has voluntarily made itself a necessary public servant, and in that capacity offers to the public its goods. While it is true that the people permit the monopoly to become a necessary public servant and protect it in the contracts by which it restricts competition, it is also true that the monopoly cannot justly make merchandise of the necessities of the people. The public may allow a combination to obtain control of all the sugar refineries, for instance, and protect the combination in its formation. But suppose the owners of the combination then say: "The people are obliged to have sugar and we control the supply. We will set a high price on sugar, therefore, because we know that they will pay it rather than go without." They are then making the necessity of the public a source of gain, and it cannot be believed that this will be permanently suffered.

The serious difficulty in fixing by direct government action the prices which a monopoly of this sort shall charge, is that we cannot stop at that point. When once the government steps in to do so radical a thing as to fix the price which a monopoly shall charge, it becomes in equity responsible to the owners of that monopoly for the maintenance of their incomes from their capital invested. If their profits have been so reduced by this action as to seriously injure the value of their property, they have a legal right to claim compensation from the state for the injury it has done them. And in almost every case they would set up the claim that their property had been thus injured. To determine the point at which reasonable prices and reasonable profits become extortionate prices and unjust profits is a task requiring expert knowledge and the most comprehensive judgment, aided by the most accurate statistics. To impose this task on our already overburdened courts would permanently block the wheels of justice, and would give to the judicial department of government a work which its machinery is wholly unsuited to carry on.

It seems evident, therefore, that when it becomes necessary for the state to directly fix prices to be charged by monopolies, a more radical step should be taken. The monopoly should be established on a permanent basis, and the state should have some part in its direct control.
