Such considerations are too general and abstract to carry conviction. Greater concreteness may be given them by comparing the present position of mine-managers with that which they would occupy were effect given to Mr. Justice Sankey's scheme for the nationalization of the Coal Industry. A body of technicians who are weighing the probable effects of such a reorganization will naturally consider them in relation both to their own professional prospects and to the efficiency of the service of which they are the working heads. They will properly take into account questions of salaries, pensions, security of status and promotion. At the same time they will wish to be satisfied as to points which, though not less important, are less easily defined. Under which system, private or public ownership, will they have most personal discretion or authority over the conduct of matters within their professional competence? Under which will they have the best guarantees that their special knowledge will carry due weight, and that, when handling matters of art, they will not be overridden or obstructed by amateurs? {166} As far as the specific case of the Coal Industry is concerned the question of security and salaries need hardly be discussed. The greatest admirer of the present system would not argue that security of status is among the advantages which it offers to its employees. It is notorious that in some districts, at least, managers are liable to be dismissed, however professionally competent they may be, if they express in public views which are not approved by the directors of their company. Indeed, the criticism which is normally made on the public services, and made not wholly without reason, is that the security which they offer is excessive. On the question of salaries rather more than one-half of the colliery companies of Great Britain themselves supplied figures to the Coal Industry Commission.[1] If their returns may be trusted, it would appear that mine-managers are paid, as a class, salaries the parsimony of which is the more surprising in view of the emphasis laid, and quite properly laid, by the mine-owners on the managers' responsibilities. The service of the State does not normally offer, and ought not to offer, financial prizes comparable with those of private industry. But it is improbable, had the mines been its property during {167} the last ten years, that more than one-half the managers would have been in receipt of salaries of under L301 per year, and of less than L500 in 1919, by which time prices had more than doubled, and the aggregate profits of the mine-owners (of which the greater part was, however, taken by the State in taxation) had amounted in five years to L160,000,000. It would be misleading to suggest that the salaries paid to mine-managers are typical of private industry, nor need it be denied that the probable effect of turning an industry into a public service would be to reduce
