But the damning difficulty with this governmental business association is, after all, in the inevitable _lack of motive_ on the part of the hired men doing the buying and selling. It is an honor to human nature, that hired men never have and never can have the zeal and enterprise of principals and owners to forecast and to perform and to lay up; because it shows that man is a rational animal, made in the image of his Maker, always acting under the pressure of personal motives, and always estimating what is his own more highly than what belongs to another. Business motives act in their fulness only on the individual, whose is the effort and whose is the return. Any policy whatever on the part of Government, which lessens the number and the eagerness of individual operators in favor of great artificial combinations resting in the shadow of the Law, lessens of necessity the gains of exchanges, and the progress of the nation, because it lessens of necessity the press of motive on the many to work and save. Government, accordingly, is quite too far off in every respect from the business, that is to say, from the buying and selling of the people, to undertake any branch of it when "it becomes necessary to abandon the principle of freedom in the establishment of enterprises." It will then be high time to "abandon" the "enterprises" themselves. If the "principle of freedom" cannot compass the "establishment of enterprises," is it likely that the "principle" of secondary and irresponsible agents can do it? To show the people how to make their bargains, how to buy and sell and save and spend, is a function government is not fitted for, was not established to perform, and never undertook without making a botch of it. In the Preamble of the Constitution of the United States there is a careful and complete and elegant enumeration of the purposes, which the body of the instrument was designed to attain. These purposes are six. No one of them contains even a hint of any purpose to enter upon the "establishment of enterprises," still less of any necessity "to abandon the principle of freedom." The last of these six purposes is phrased: "AND TO SECURE THE BLESSINGS OF LIBERTY TO OURSELVES AND OUR POSTERITY." The liberty to buy and sell freely was precisely that "liberty" of the Colonies which was most threatened and infringed by the British Government, to vindicate that special "liberty" was the chief cause of the American Revolution, and "to secure the blessings" of that and other forms of similar "liberty" was the final purpose of the Constitution of the United States.
