When we are fed and clothed and housed, further material goods are needed only for ostentation.[12] With modern methods, a certain proportion of the population, without working long hours, could do all the work that is really necessary in the way of producing commodities. The time which is now spent in producing luxuries could be spent partly in enjoyment and country holidays, partly in better education, partly in work that is not manual or subserving manual work. We could, if we wished, have far more science and art, more diffused knowledge and mental cultivation, more leisure for wage-earners, and more capacity for intelligent pleasures. At present not only wages, but almost all earned incomes, can only be obtained by working much longer hours than men ought to work. A man who earns £800 a year by hard work could not, as a rule, earn £400 a year by half as much work. Often he could not earn anything if he were not willing to work practically all day and every day. Because of the excessive belief in the value of production, it is thought right and proper for men to work long hours, and the good that might result from shorter hours is not realized. And all the cruelties of the industrial system, not only in Europe but even more in the tropics, arouse only an occasional feeble protest from a few philanthropists. This is because, owing to the distortion produced by our present economic methods, men’s conscious desires, in such matters, cover only a very small part, and that not the most important part, of the real needs affected by industrial work. If this is to be remedied, it can only be by a different economic system, in which the relation of activity to needs will be less concealed and more direct. The purpose of maximizing production will not be achieved in the long run if our present industrial system continues. Our present system is wasteful of human material, partly through damage to the health and efficiency of industrial workers, especially when women and children are employed, partly through the fact that the best workers tend to have small families and that the more civilized races are in danger of gradual extinction. Every great city is a center of race-deterioration. For the case of London this has been argued with a wealth of statistical detail by Sir H. Llewelyn Smith;[13] and it cannot easily be doubted that it is equally true in other cases. The same is true of material resources: the minerals, the virgin forests, and the newly developed wheatfields of the world are being exhausted with a reckless prodigality which entails almost a certainty of hardship for future generations.
