The mechanism of modern business is so delicate that extreme care must be taken not to interfere with it in a spirit of rashness or ignorance. Many of those who have made it their vocation to denounce the great industrial combinations which are popularly, although with technical inaccuracy, known as "trusts," appeal especially to hatred and fear. These are precisely the two emotions, particularly when combined with ignorance, which unfit men for the exercise of cool and steady judgment. In facing new industrial conditions, the whole history of the world shows that legislation will generally be both unwise and ineffective unless undertaken after calm inquiry and with sober self-restraint. Much of the legislation directed at the trusts would have been exceedingly mischievous had it not also been entirely ineffective. In accordance with a well-known sociological law, the ignorant or reckless agitator has been the really effective friend of the evils which he has been nominally opposing. In dealing with business interests, for the Government to undertake by crude and ill-considered legislation to do what may turn out to be bad, would be to incur the risk of such far-reaching national disaster that it would be preferable to undertake nothing at all. The men who demand the impossible or the undesirable serve as the allies of the forces with which they are nominally at war, for they hamper those who would endeavor to find out in rational fashion what the wrongs really are and to what extent and in what manner it is practicable to apply remedies. All this is true; and yet it is also true that there are real and grave evils, one of the chief being over-capitalization because of its many baleful consequences; and a resolute and practical effort must be made to correct these evils. There is a widespread conviction in the minds of the American people that the great corporations known as trusts are in certain of their features and tendencies hurtful to the general welfare. This springs from no spirit of envy or uncharitableness, nor lack of pride in the great industrial achievements that have placed this country at the head of the nations struggling for commercial supremacy. It does not rest upon a lack of intelligent appreciation of the necessity of meeting changing and changed conditions of trade with new methods, nor upon ignorance of the fact that combination of capital in the effort to accomplish great things is necessary when the world's progress demands that great things be done. It is based upon sincere conviction that combination and concentration should be, not prohibited, but supervised and within reasonable limits controlled; and in my judgment this conviction is right.
