The common good, so far as it is a question of material welfare, is evidently best served by an unhampered working of the industrial system at its full capacity, without interruption or dislocation. But it is equally evident that the owner or manager of any given concern or section of this industrial system may be in a position to gain something for himself at the cost of the rest by obstructing, retarding or dislocating this working system at some critical point in such a way as will enable him to get the best of the bargain in his dealings with the rest.
