Among savages, mere physical strength, on the part of one man, may enable him to rob, enslave, or kill another man. Among barbarians, mere physical strength, on the part of a body of men, disciplined, and acting in concert, though with very little money or other wealth, may, under some circumstances, enable them to rob, enslave, or kill another body of men, as numerous, or perhaps even more numerous, than themselves. And among both savages and barbarians, mere want may sometimes compel one man to sell himself as a slave to another. But with (so-called) civilized peoples, among whom knowledge, wealth, and the means of acting in concert, have become diffused; and who have invented such weapons and other means of defense as to render mere physical strength of less importance; and by whom soldiers in any requisite number, and other instrumentalities of war in any requisite amount, can always be had for money, the question of war, and consequently the question of power, is little else than a mere question of money. As a necessary consequence, those who stand ready to furnish this money, are the real rulers. It is so in Europe, and it is so in this country.
