There are from one-quarter to three-quarters of a million of preventable deaths every years in this country. That number of individuals could have been saved with proper care and attention to health in the early stages of disease, or before it gained a start. Practically all the diseases that carry business men off prematurely are curable in the early stages. Of the percentage of Wall Street men who need medical attention immediately, most have kidney or heart disease. The others are victims of typical unhygienic habits, such as fast, gluttonous eating, neglect of exercise, too much tobacco and liquor, and bad posturing in the office. The business man considers these trifles, but they count heavily. Business efficiency is greatly increased, first, by selecting men physically fit for work, and, second, by keeping them in that condition. There is a tremendous waste from inefficiency constantly going on, due to impaired health. Wall Street has an astonishing corps of neurasthenics. We need a broader interpretation of the term Eugenics, so that we may gain a more sympathetic and tolerant audience. The remedy does not lie in an academic discussion of these problems; to continue the debate behind closed doors will not lead anywhere: the public must be educated to a just appreciation of existing conditions and the remedy must be the product of effort on its part. Any condition that fundamentally means race deterioration must be [xxvii] rendered intolerable. The prevalant dancing craze is an anti-eugenic institution, as is the popularity of the delicatessen store. No sane person can regard with complacency the vicious environment in which the future mothers of the race "tango" their time, their morals, and their vitality away. We do not assume to pass judgment on the merits of the dance; we do, however, emphatically condemn the surroundings. The moving-picture shows, vaudeville entertainments, dancing carnivals, the ease of travel, the laxity of laws, the opportunities for promiscuous interviews, all tend to give youth a false impression of the reality of life and to make the path of the degenerate easy and attractive.
