Moneyed capital I take to be stored human energy, as a coal measure is stored solar energy; and moneyed capital, under the stress of modern life, has developed at once extreme fluidity, and an equivalent compressibility. Thus a small number of men can control it in enormous masses, and so it comes to pass that, in a community like the United States, a few men, or even, in certain emergencies, a single man, may become clothed with various of the attributes of sovereignty. Sovereign powers are powers so important that the community, in its corporate capacity, has, as society has centralized, usually found it necessary to monopolize them more or less absolutely, since their possession by private persons causes revolt. These powers, when vested in some official, as, for example, a king or emperor, have been held by him, in all Western countries at least, as a trust to be used for the common welfare. A breach of that trust has commonly been punished by deposition or death. It was upon a charge of breach of trust that Charles I, among other sovereigns, was tried and executed. In short, the relation of sovereign and subject has been based either upon consent and mutual obligation, or upon submission to a divine command; but, in either case, upon recognition of responsibility. Only the relation of master and slave implies the status of sovereign power vested in an unaccountable superior. Nevertheless, it is in a relation somewhat analogous to the latter, that the modern capitalist has been placed toward his fellow citizens, by the advances in applied science. An example or two will explain my meaning. High among sovereign powers has always ranked the ownership and administration of highways. And it is evident why this should have been so. Movement is life, and the stoppage of movement is death, and the movement of every people flows along its highways. An invader has only to cut the communications of the invaded to paralyze him, as he would paralyze an animal by cutting his arteries or tendons. Accordingly, in all ages and in all lands, down to the nineteenth century, nations even partially centralized have, in their corporate capacity, owned and cared for their highways, either directly or through accountable agents. And they have paid for them by direct taxes, like the Romans, or by tolls levied upon traffic, as many mediaeval governments preferred to do. Either method answers its purpose, provided the government recognizes its responsibility; and no government ever recognized this responsibility more fully than did the autocratic government of ancient Rome. So the absolute régime of eighteenth-century France recognized this responsibility when Louis XVI undertook to remedy the abuse of unequal taxation, for the maintenance of the highways, by abolishing the corvée.
