1. We hold that it is to the interests of the United States, for the reasons given in this chapter, to prevent further Negro-white amalgamation.
2. The taboo of public opinion is not sufficient in all cases to prevent intermarriage, and should be supplemented by law, particularly as the United States have of late years received many white immigrants from other countries (e. g., Italy) where the taboo is weak because the problem has never been pressing.
3. But to prevent intermarriage is only a small part of the solution, since most mulattoes come from extramarital miscegenation. The only solution of this, which is compatible with the requirements of eugenics, is not that of laissez faire, suggested by the National Association, but an extension of the taboo, and an extension of the laws, to prohibit all sexual intercourse between the two races.
Four states (Louisiana, Nevada, South Dakota and Alabama) have already attempted to gain this end by law. We believe it to be highly desirable that such laws should be enacted and enforced by all states. A necessary preliminary would be to standardize the laws all over the Union, particularly with a view to agreement on what a "Negro" legally is; for in some states the legislation applies to one who is one-sixteenth, or even less, Negro in descent, while in other states it appears to refer only to full-blood or, at the most, half-blood individuals.
Such legislation, and what is more important, such public opinion, leading to a cessation of Negro-white amalgamation, we believe to be in the interests of national eugenics, and to further the welfare of both of the races involved. Miscegenation can only lead to unhappiness under present social conditions and must, we believe, under any social conditions be biologically wrong.
We favor, therefore, the support of the taboo which society has placed on these mixed marriages, as well as any legal action which can practicably be taken to make miscegenation between white and black impossible. Justice requires that the Negro race be treated as kindly and considerately as possible, with every economic and political concession that is consistent with the continued welfare of the nation. Such social equality and intercourse as might lead to marriage are not compatible with this welfare.
CHAPTER XV
IMMIGRATION
There are now in the United States some 14,000,000 foreign-born persons, together with other millions of the sons and daughters of foreigners who although born on American soil have as yet been little assimilated to Americanism. This great body of aliens, representing perhaps a fifth of the population, is not a pool to be absorbed, but a continuous, inflowing stream, which until the outbreak of the Great War was steadily increasing in volume, and of which the fountain-head is so inexhaustible as to appal the imagination. From the beginning of the century, the inflow averaged little less than a million a year, and while about one-fifth of this represented a temporary migration, four-fifths of it meant a permanent addition to the population of the New World.
