Of some of these I have spoken already; the alarming drift towards cities, until now in the United States more than one-half the population is urban; the segregation of industries in certain cities and regions; the minute division of labour and intensive specialization; the abnormal growth of a true proletariat or non-land-holding class; the flooding of the country by cheap labour drawn from the most backward communities and from peoples of low race-value. Out of this has arisen a bitter class conflict and the ominous beginnings of a perilous class consciousness, with actual warfare joined in several countries, and threatened in all others where industrial civilization is prevalent. With this has grown up an artificially stimulated covetousness for a thousand futile luxuries, and a standard of living that presupposes a thousand non-essentials as basic necessities. Production for profit, not use, excess production due to machinery, efficient organization, and surplus of labour, together with the necessity for marketing the product at a profit, have produced a state of things where at least one-half the available labour in the country is engaged in the production and sale of articles which are not necessary to physical, intellectual or spiritual life, while of the remainder, hardly more than a half is employed in production, the others are devoting themselves to distribution and to the war of competition through advertising and the capturing of trade by ingenious and capable salesmen. It is a significant fact that two of the greatest industries in the United States are the making of automobiles and moving pictures. It is probably true to say that of the potential labour in the United States, about one-fourth is producing those things which are physically, intellectually and spiritually necessary; the remaining three-fourths are essentially non-producers: they must, however, be housed, fed, clothed, and amused, and the cost of this support is added to the cost of the necessities of life. The reason for the present high cost of living lies possibly here.
