Yet it might be argued that each concrete article of "capital goods" was the product of some one man's labor, and, as such, its productivity, when put to use, was but the indirect, ulterior, deferred productiveness of the maker's labor. But the maker's productivity in the case was but a function of the immaterial technological equipment at his command, and that in its turn was the slow spiritual distillate of the community's time-long experience and initiative. To the individual producer or owner, to whom the community's accumulated stock of immaterial equipment was open by common notoriety, the cost of the concrete material goods would be the effort involved in making or getting them and in making good his claim to them. To his neighbor who had made or acquired no such parcel of "productive goods," but to whom the resources of the community, material and immaterial, were open on the same easy terms, the matter would look very much the same. He would have no grievance, nor would he have occasion to seek one. Yet, as a resource in the maintenance of the community's life and a factor in the advance of material civilisation, the whole matter would have a different meaning. So long, or rather in so far, as the "capital goods" required to meet the technological demands of the time were slight enough to be compassed by the common man with reasonable diligence and proficiency, so long the draft upon the common stock of immaterial assets by any one would be no hindrance to any other, and no differential advantage or disadvantage would emerge. The economic situation would answer passably to the classical theory of a free competitive system,--"the obvious and simple system of natural liberty," which rests on the presumption of equal opportunity. In a roughly approximate way, such a situation supervened in the industrial life of western Europe on the transition from mediaeval to modern times, when handicraft and "industrial" enterprise superseded landed wealth as the chief economic factor. Within the "industrial system," as distinct from the privileged non-industrial classes, a man with a modicum of diligence, initiative, and thrift might make his way in a tolerable fashion without special advantages in the way of prescriptive right or accumulated means. The principle of equal opportunity was, no doubt, met only in a very rough and dubious fashion; but so favorable became the conditions in this respect that men came to persuade themselves in the course of the eighteenth century that a substantially equitable allotment of opportunities would result from the abrogation of all prerogatives other than the ownership of goods. But so precarious and transient was this approximation to a technologically feasible system of equal opportunity that, while the liberal movement which converged upon this great economic reform was still gathering head, the technological situation was already outgrowing the possibility of such a scheme of reform.
