“This is not to say that other causes do not contribute to lower the birth-rate of a country, for that is an almost world-wide phenomenon. But the desire to be separated from inferiors is as strong a motive to birth-control as the desire for luxury or to ape one’s economic superiors. Races follow Gresham’s law as to money: the poorer of two kinds in the same place tends to supplant the better. Mark you, supplant, not drive out. One of the most common fallacies is the idea that the natives whose places are taken by the lower immigrants are ‘driven up’ to more responsible positions. A few may be pushed up; more are driven to a new locality, as happened in the mining regions; but most are prevented from coming into existence at all.
“What is the result, then, of the migration of 1,000,000 persons of lower level into a country where the average is of a higher level? Considering the world as a whole, there are, after a few years, 2,000,000 persons of the lower type in the world, and probably from 500,000 to 1,000,000 less of the higher type. The proportion of lower to higher in the country from which the migration goes may remain the same; but in the country receiving it, it has risen. Is the world as a whole the gainer?
“Of course the euthenist[151] says at once that these immigrants are improved. We may grant that, although the improvement is probably much exaggerated. You cannot make bad stock into good by changing its meridian, any more than you can turn a cart-horse into a hunter by putting it into a fine stable, or make a mongrel into a fine dog by teaching it tricks. But such improvement as there is involves time, expense, and trouble; and, when it is done, has anything been gained? Will any one say that the races that have supplanted the old Nordic stock in New England are any better, or as good, as the descendants of that stock would have been if their birth-rate had not been lowered?
“Further, in addition to the purely biological aspects of the matter, there are certain psychological ones. Although a cosmopolitan atmosphere furnishes a certain freedom in which strong congenital talents can develop, it is a question whether as many are not injured as helped by this. Indeed, there is considerable evidence to show that for the production of great men, a certain homogeneity of environment is necessary. The reason of this is very simple. In a homogeneous community, opinions on a large number of matters are fixed. The individual does not have to attend to such things, but is free to go ahead on some special line of his own, to concentrate to his limit on his work, even though that work be fighting the common opinions.
“But in a community of many races, there is either cross-breeding or there is not. If there is, the children of such cross-breeding are liable to inherit two souls, two temperaments, two sets of opinions, with the result in many cases that they are unable to think or act strongly and consistently in any direction. The classic examples are Cuba, Mexico, and Brazil. On the other hand, if there is no cross-breeding, the diversity exists in the original races, and in a community full of diverse ideals of all kinds much of the energy of the higher type of man is dissipated in two ways. First, in the intellectual field there is much more doubt about everything, and he tends to weigh, discuss, and agitate many more subjects, in order to arrive at a conclusion amid the opposing views. Second, in practical affairs, much time and strength have to be devoted to keeping things going along old lines, which could have been spent in new research and development. In how many of our large cities to-day are men of the highest type spending their whole time fighting, often in vain, to maintain standards of honesty, decency, and order, and in trying to compose the various ethnic elements, who should be free to build new structures upon the old!
“The moral seems to be this: Eugenics among individuals is encouraging the propagation of the fit, and limiting or preventing the multiplication of the unfit. World-eugenics is doing precisely the same thing as to races considered as wholes. Immigration restriction is a species of segregation on a large scale, by which inferior stocks can be prevented from both diluting and supplanting good stocks. Just as we isolate bacterial invasions, and starve out the bacteria by limiting the area and amount of their food-supply, so we can compel an inferior race to remain in its native habitat, where its own multiplication in a limited area will, as with all organisms, eventually limit its numbers and therefore its influence. On the other hand, the superior races, more self-limiting than the others, with the benefits of more space and nourishment will tend to still higher levels.
“This result is not merely a selfish benefit to the higher races, but a good to the world as a whole. The object is to produce the greatest number of those fittest not ‘for survival’ merely, but fittest for all purposes. The lower types among men progress, so far as their racial inheritance allows them to, chiefly by imitation and emulation. The presence of the highest development and the highest institutions among any race is a distinct benefit to all the others. It is a gift of psychological environment to any one capable of appreciation.”[152]
The impossibility of any advanced and prosperous community maintaining its social standards and handing them down to its posterity in these days of cheap and rapid transportation except by restrictions upon immigrations is thus explained by Professor Ross: “Now that cheap travel stirs the social deeps and far-beckoning opportunity fills the steerage, immigration becomes ever more serious to the people that hopes to rid itself at least of slums, ‘masses,’ and ‘submerged.’ What is the good of practising prudence in the family if hungry strangers may crowd in and occupy at the banquet table of life the places reserved for its children? Shall it, in order to relieve the teeming lands of their unemployed, abide in the pit of wolfish competition and renounce the fair prospect of growth in suavity, comfort, and refinement? If not, then the low-pressure society must not only slam its doors upon the indraft, but must double-lock them with forts and iron-clads, lest they be burst open by assault from some quarter where ‘cannon food’ is cheap.”[153]
These admirable summaries of the immigration problem in its world-aspect are strikingly illustrated by our own country, which may be considered as the leading, if not the “horrible,” example. Probably few persons fully appreciate what magnificent racial treasures America possessed at the beginning of the nineteenth century. The colonial stock was perhaps the finest that nature had evolved since the classic Greeks. It was the very pick of the Nordics of the British Isles and adjacent regions of the European continent—picked at a time when those countries were more Nordic than now, since the industrial revolution had not yet begun and the consequent resurgence of the Mediterranean and Alpine elements had not taken place.
The immigrants of colonial times were largely exiles for conscience’s sake, while the very process of migration was so difficult and hazardous that only persons of courage, initiative, and strong will-power would voluntarily face the long voyage overseas to a life of struggle in an untamed wilderness haunted by ferocious savages.
