In the abstract, it is impossible to balance these various possibilities with complete assurance. The only inductive studies of value which give any indication of the probable result are those which have been made upon the results of living wage legislation. These, almost without exception, make the price increase resulting from standardization, inconsiderable.[83] They are witness to the fact that improvements in the level of industrial management and a gradual elimination of the less competent employers have frequently taken place. The opinion seems warranted that unless standardization is introduced under very unfavorable circumstances or in the form of an extremely violent upward movement, it will not cause a considerable or permanent rise of prices, but will rather bring improvement in industrial organization and lead to a more intelligent use of labor in industry. Along with this, there is reason to hope that it will have a favorable reaction on the efforts of the wage earners. 8.--The whole subject of the effect of wage standardization upon the output of the wage earners remains to be considered, however. It is an aspect of the subject which has been in the forefront of discussion. It also is a topic which cannot be satisfactorily discussed apart from a larger one--that of the effect of unionism upon production. The most bitter opposition to trade unionism has been connected with allegations made in this regard. These have taken different forms, but they almost always express one contention. That is that if a standard wage is set for work of a given kind, and if all men engaged upon that work receive that wage irrespective of small differences in ability, there will remain no stimulus for the abler workmen to exert themselves. Or in other words, that the standard wage makes slackers of all men. Sometimes this criticism is leveled only against the standard time wage; at other times against the standard guaranteed minimum wage, such as there used to be in the English coal fields; and, at still other times, against any method of wage payment which takes full power out of the hands of the employers to make an individual wage bargain with each worker. These contentions have some basis on occasion. More often they arise from a misconception of the place of the wage earner in industry, or from a general hostility to labor unionism. Wage standardization does not mean that all wage earners receive the same wage irrespective of differences in ability. It simply sets a minimum standard for all workers of the group who are about the average in ability. It is designed to end all differences in remuneration, save those which arise out of differences in ability. It may be worked out in systems of payment by results, as well as in systems of time payment.
