It will be argued, at a later point, that under any economic system in which labor organization is an accepted part of the economic structure, the wage levels established in different industries or occupations will have to be brought into relation with each other.[108] If that is so, the level of standardization of any industry or occupation would be determined in accordance with these principles, after they had been in operation for some time. As a matter of fact, however, under any policy of wage settlement, the enforcement of standardization will be something of an independent and prior process--prior, that is, to the application of any other principles intended to keep the wage levels in different industries or occupations in relation to each other. Standardization will be, so to speak, an initial stage of policy to be gone through before any other stages are entered upon. In this initial stage, the principal data that should be taken into consideration when fixing the level of standardization for any occupation is the actually existing variety of wage rates for that occupation. Where in the scale of actually existing rates the level of standardization is set must be a matter of judgment and compromise. That level of standardization should be chosen, which it is believed will produce more good and less harm than any other level that might be chosen. Or in other words, the level of standardization should be determined by a balance of the interests involved--that point being chosen at which, it is judged, the most favorable balance is established. There is current, indeed, one doctrine of standardization which holds that there is but one satisfactory level of standardization for an occupation in which wages have been hitherto unstandardized. That doctrine, crudely stated, is that the standard wage for the work in question should be the highest of the unstandardized wages.[109] That doctrine is called "standardization upward."
