Disaster, in the form of famine, pestilence, tidal waves, earthquakes or war, sometimes limits the number of available workers. Then those who live in parts of the world that are not affected, or who stay at home during wars, reap a temporary advantage. These advantages, however, are quickly offset by increased prices, or by competition for jobs when soldiers return from war. This form of limitation of numbers works to the advantage of labor as long as it is available, but great disasters are not constantly in operation while the worker's reproductive ability is. So in a few years they have lost what nature's destructiveness won for them. The great mass of the workers--including children and women--are unskilled and unorganized. Not only that, they are for some considerable part of the time seeking employment. They are, of course, poorly paid. Thus, through their low wages and their seeking of employment, they always come into direct competition with one another and with the skilled and organized workmen. As their families live in want and are often diseased, they create the chief social problems of the day. They bring children into the world as fast as women can bear them. With each child they increase their own misery and provide another worker to force down wages and prolong hours, through competition for employment. This has been the way of labor from the beginning. It is labor's way in every country. Having discovered that there is no relief in legislation, labor organizes to limit its numbers in certain trades. Meanwhile the women of the working class go on breeding more workers to wipe out in the future the advantages gained for the present. In Paris, for instance, the proletarian quarters of the city show a birth rate more than three times as high as the birth rate in the well-to-do sections. "Dr. Jacques Bartillon furnishes us with statistics which prove that the birth rate in any quarter of Paris is in inverse ratio to its degree of affluence," says G. Hardy in _How to Prevent Pregnancy_. "The rich Champs-Elysees has a birth rate a third of that Bellerville or of the Buttes-Chaumont. From 1,000 women from the age of fifteen to fifty, Menimontant gives 116 births; the Champs-Elysees thirty-four births. "It is the same in Berlin. For 1,000 women from the age of fifteen to that of fifty, a very poor quarter gives 157 births; a rich quarter gives 47 births." And so it is the world over. The very word "proletarian," as Hardy points out, means "producer of children." The children thus carelessly produced undermine the health of the mother, deepen the family's poverty, destroy the happiness of the home, and dishearten the father; all this in addition to being future competitors in the labor market. Too often their increasing number drives the mother herself into industry, where her beggarly wages tend to lower the level of those of her husband.
