But wait. Now we want to know how the _other_ half lives: Society is a whole, not a half. These great questions are questions of society, and they can not be answered by investigating _half_ of society. Yes, we want to know about the $2,000,000 that was paid in wages; to whom it went, and how it was spent, but we also want to know about the $7,000,000 that was paid in dividends. To whom did _it_ go, and how was _it_ spent? How much did the dividend receivers need a week on which to live? Were they judicious in their expenditures? These questions also ought to be investigated by a commission. What do we know about the occupations, the health, the morality, the family life of the very rich? If we are suspicious that the home life of the children of Mrs. Zambrowski of Mulberry street is not all that could be desired, we send a juvenile court officer to investigate. If there is evidence that the father is not honestly employed, if there is disease in the household, some officer is on hand to see what is the matter. What do we know of the home life of the Van Astor children? Is Mr. Van Astor an industrious bread earner? Are the home conditions of the Van Astor children morally healthful? We want to know more about these excursions to Europe. Are they always cultural? We want to know more about the life of Mrs. Astorbilt in her Paris home. We want to know more about the employment conditions of the “Four Hundred.” Perhaps a law should be made in the interests of health limiting the number of continuous hours spent in certain social activities. We want to know more about the lives of boys and girls in wealthy boarding-schools. We desire to find out just how a working girl spends $8 a week, but we also wish to learn just how the dividend receiver spends $800 a week. The poor need visiting housekeepers to instruct them, but may not the wealthy need visiting home-keepers? The unexplored continent of sociology is the life of the wealthy. It is to the interest of the health and well-being of society that a careful and dispassionate study be made of this subject. CLARENCE D. BLACHLY. Chicago. A CALL FOR LEADERSHIP TO THE EDITOR: There is a widespread opinion among social and industrial workers that the unequal conditions existing in human society are going to be levelled: that equality of opportunity and the more equitable distribution of the necessities of life are to be accomplished by a system of “passing it on.” In this way, the social burden, instead of resting where it does now, on the lowest stratum of the population, will be placed on broad shoulders better able to bear the load. Do not such solutions as employers’ liability, workmen’s compensation, the minimum wage, reduced hours of employment and better occupational conditions all mean an increase in the cost of producing the necessaries of life? Do they not tend to make more grave one of the vital problems of the hour?
