Lastly, it is possible, and indeed necessary so to frame policy, that even while it maintains peace and produces cooperation between conflicting interests and ideas, it does not stereotype forever the terms of peace and cooperation. Agreement is often obtained for an economic or political policy in the knowledge that it can be changed if different ideas come to prevail. A policy of wage adjustment, like any other measure, would have to be always subject to reconsideration and amendment. Indeed, it might carry provision in itself for such reconsideration; it might be adopted as an experiment for a definite period of years. 2.--In the preceding chapters the main problems that must arise in the course of any attempt to settle wages by official authority have been discussed. These problems were considered with reference to the possible formulation of a satisfactory policy of wage settlement for industrial peace. That policy may now be presented as a whole. Only in that way, indeed, can the significance of any particular principle of settlement be understood. It is presumed that whatever policy is put into force will be administered by a government agency, with and by the consent and support of both the wage earners and the employers. It is also presumed that the method of collective bargaining is accepted throughout industry. Indeed, the existence of organized joint boards or councils of wage earners and employers would be almost essential to the success of any policy. The central constituted agency for the administration of the policy should be a commission or court. The policy should then provide that whenever a dispute arises incidental to the settlement of wages in any industry included within the scope of the policy, which dispute is not settled by the ordinary course of collective bargaining, it should be referred to this commission or court. All sides should be permitted to submit evidence bearing upon the case. The court or commission should have its own expert staff, and its own record and statistical office; and it should be its duty to know the wage situation throughout industry.[152] Every possible effort should be made by the commission or court to render judgment without litigation. The commission or court should give in full the principles and the data upon which it bases its decisions. The wage policy of the commission or court should rest upon the following principles: _First_--The principle of standardization should be applied throughout industry. Wages should be standardized by occupations, despite minor differences in the character of the work performed by the same occupational group, or in the conditions under which the work is performed. Standard rates should be understood to be merely minimum rates; and the principle of standardization should be construed so as to permit of all methods of wage payment.
