One of the strongest arguments that could be adduced by the founders of the American Constitution in favor of the establishment of a more perfect union was that the inequality of taxes placed upon commerce by the various States was a serious obstacle to its free development. Much as the individual States dislike to give up a part of their sovereignty to a central or national power, the demand for a common and uniform system of commercial taxation was so great that they were forced to yield and ratify the new Constitution. Our forefathers thus considered it a dangerous policy to permit a single State to lay any imposts upon the commercial commodities which passed over its borders. They were rightly of the opinion that industrial and commercial liberty was as essential to the welfare of the nation as political freedom and that therefore interstate commerce should not be hemmed in or controlled within State lines, but that the power to regulate it should be lodged in the supreme legislative authority of the nation, the Congress of the United States. For over half a century Congress alone exercised the power thus conferred upon it by the people. After the introduction of railroads, however, their managers gradually assumed the right to regulate the commerce of the country in their own interest through the adoption of arbitrary freight tariffs. Freight charges are practically a tax which follows the commodity from the producer to the consumer. An arbitrary and unjust charge is therefore an arbitrary and unjust tax imposed upon the public without its consent. It is a well-established rule of society that laws should be equitable and just to all citizens. Congress never assumed the role of Providence by attempting to equalize those differences among individuals which superior intellect, greater industry and a thousand other uncontrollable forces have ever created and will ever create. It has been reserved to railroad managers to demonstrate to the public that a power has been allowed to grow up which has assumed the right to counteract the dispensations of Providence, to enrich the slothful, to impoverish the industrious, to curtail the profits of remunerative industries and revive by bounties those languishing for want of vitality, to humble proud and self-reliant marts of trade and to build up cities in the desert. It will scarcely be claimed even by railroad managers that their policy of thus arbitrarily regulating commerce originated in philanthropic motives. They are forced to admit that it grew out of an attempt to increase the income of railroads by the extension of favors to naturally weak enterprises and to recoup by overtaxing stronger ones.
