¶The first essential in determining how to deal with the great industrial combinations is knowledge of the facts—publicity. In the interest of the public, the Government should have the right to inspect and examine the workings of the great corporations engaged in interstate business. Publicity is the only sure remedy which we can now invoke. What further remedies are needed in the way of governmental regulation, or taxation, can only be determined after publicity has been obtained, by process of law, and in the course of administration. The first requisite is knowledge, full and complete—knowledge which may be made public to the world. ¶Artificial bodies, such as corporations and joint-stock or other associations, depending upon any statutory law for their existence or privileges, should be subject to proper governmental supervision, and full and accurate information as to their operations should be made public regularly at reasonable intervals. ¶The large corporations, commonly called trusts, though organized in one State, always do business in many States, often doing very little business in the State where they are incorporated. There is utter lack of uniformity in the State laws about them; and as no State has any exclusive interest in or power over their acts, it has in practice proved impossible to get adequate regulation through State action. Therefore, in the interest of the whole people, the Nation should, without interfering with the power of the States in the matter itself, also assume power of supervision and regulation over all corporations doing an interstate business. This is especially true where the corporation derives a portion of its wealth from the existence of some monopolistic element or tendency in its business. There would be no hardship in such supervision; banks are subject to it, and in their case it is now accepted as a simple matter of course. Indeed, it is probable that supervision of corporations by the National Government need not go so far as is now the case with the supervision exercised over them by so conservative a State as Massachusetts, in order to produce excellent results.
