Neither this people nor any other free people will permanently tolerate the use of the vast power conferred by vast wealth, and especially by wealth in its corporate form, without lodging somewhere in the Government the still higher power of seeing that this power, in addition to being used in the interest of the individual or individuals possessing it, is also used for and not against the interests of the people as a whole. Our peculiar form of government, a Government in which the Nation is supreme throughout the Union in certain respects, while each of nearly half a hundred States is supreme in its part of the Union in certain other respects, renders the task of dealing with these conditions especially difficult. No finally satisfactory result can be expected from merely State action. The action must come through the Federal Government. The business of the country is now carried on in a way of which the founders of our Constitution could by no possibility have had any idea. All great business concerns are engaged in interstate commerce, and it was beyond question the intention of the founders of our Government that interstate commerce in all its branches and aspects should be under national and not State control. If the courts decide that this intention was not carried out and made effective in the Constitution as it now stands, then in the end the Constitution, if not construed differently, will have to be amended so that the original undoubted intention may be made effective. But, of course, a constitutional amendment is only to be used as a last resort, if every effort of legislation and administration shall have been proved inadequate. Meanwhile the men in public life and the men who direct the great business interests of the country should work not in antagonism but in harmony toward this given end. In entering a field where the progress must of necessity be so largely experimental it is essential that the effort to make progress should be tentative and cautious. We must grow by evolution, not by revolution. There must be no hurry, but there must also be no halt; and those who are anxious that there should be no sudden and violent changes must remember that precisely these sudden and violent changes will be rendered likely if we refuse to make the needed changes in cautious and moderate manner.
