A few concrete illustrations[78] will show the lack of correspondence between the political system and the economic system. Each state bids against the others to increase the number of factories which adds to its wealth and increases the value of property within its borders, although it makes no difference to the total wealth of the nation and the happiness of the whole people whether a particular concern is located in New Jersey or in Pennsylvania. As the national government enjoys no power to regulate industries--even those which are national in character--the states use their respective powers under the pressure which comes from those who are interested in increasing the industry of the commonwealth. For example, it is stated "the glass workers of New Jersey oppose any attempt to prohibit night work for boys under sixteen years of age on the ground that such work is permitted in the neighboring state of Pennsylvania." In 1907, in South Carolina, Georgia, and Alabama, a ten year old child could, under the law, work for twelve hours a day; North Carolina had sixty-six mills where twelve year old children could do twelve hours' night work under the law. Although this situation was somewhat remedied later, the advocates of reform were resisted at every point by the interested parties who contended that in competing with New England, the southern states had to take advantage of every opportunity, even at the expense of the children. The situation may be described in the language of the chief factory inspector of Ohio: "Industrially as well as geographically we of the Ohio Valley are one people and our laws should be uniform, not only that they may be the easier enforced, but in justice to the manufacturers who pursue the same industry in the several states and therefore come into close competition with one another." Moreover, if a state enacts an important industrial law, it may find its work in vain as the result of a decision of the national Supreme Court, or of the state courts, interpreting the Fourteenth Amendment.
