But knowledge and training are not all that is wanted. It is essential that all classes connected with industry should realise that increased production in established and well-understood industries is essential, and that it can only be obtained, first, by willing and vigorous work on the part of the workman, aiming at producing as much as possible in the hours during which labour can be efficiently carried on without detriment to health or depriving the labourer of the opportunities of enjoying a life outside his daily routine; and, secondly, by the increased use of the best machinery and labour-saving appliances and working such machinery to its fullest capacity. Instead of that, it has often been the policy to restrict the production of each man's labour, one reason being lest there should not be enough employment to go round, and also to view the introduction of machinery which might displace labour with hostility and suspicion. In order to give the leisure which the workman needs for a full and healthy life, and to provide a wage which will enable him to secure the comforts which he rightly desires, as well as to obtain adequate remuneration for those who manage businesses, and interest on their money for those whose capital is to be embarked in them, increased production is necessary; but it cannot be expected that workmen will realise this or desire the result unless they know certainly that they will obtain at once a benefit from it. It has too often been the case that where some new invention has been made, or new machinery introduced, or the conditions of trade have enabled an industry to be more profitable, the workman has not shared in the benefits obtained until he has pressed for an increase of wages, even to the extent of striking or threatening to strike. The faults and jealousies leading to restricted production are not all on one side. Cases have arisen when a manager has let out a piece of work to a group of workmen at a price which has resulted in a larger output in a given time at less cost, though the amount paid to each man has been higher owing to increased diligence, yet the employers raised objections, because the wages earned were "more than such men ought to have."
