It may be that wary beasts of the forest come around to accepting the hunter's trap as a necessary concomitant of foraging for food. At any rate, the presumably rational human animal has become so inured to political interventions that he cannot think of the making of a living without them; in all his economic calculations his first consideration is, what is the law in the matter? Or, more likely, how can I make use of the law to improve my lot in life? This may be described as a conditioned reflex. It hardly occurs to us that we might do better operating under our own steam, within the limits put upon us by nature, and without political restraints, controls, or subventions. It never enters our minds that these interventionary measures are placed in our path, like the trap, for purposes diametrically opposed to our search for a better living. We automatically accept them as necessary to that purpose.
And so it has come to pass that those who write about economics begin with the assumption that it is a branch of political science. Our current textbooks, almost without exception, approach the subject from a legal standpoint: how do men make a living under the prevailing laws? It follows, and some of the books admit it, that if the laws change, economics must follow suit. It is for that reason that our college
