Richard Lynn writes in his book Eugenics:
Third, costs arose because many immigrants into the Western democracies are from third world countries whose populations differ racially and culturally from the indigenous populations. This inevitably causes racial and ethnic conflict and the development of legislation and a bureaucracy that attempted to contain these conflicts. This causes resentment, which the indigenous populations endeavor to defuse by affirmative action and equal opportunity policies in admission to universities and employment. These in turn generated resentment among the indigenous population, some of whom are refused admission to universities, excluded from employment, and deprived of career advancement on the grounds that they are white. These problems have been examined by Gerald Scully (1995) in a study published by the American National Center for Policy Analysis. He concluded that ‘‘countries with a common culture are more likely than culturally diverse nations to be economically prosperous and to offer their citizens more personal freedom … ; we find that where there are multiple cultures there is almost always conflict” (Lutton, 1999, p. 271). The same verdict is reached by LaPorto, Lopez-de-Silanes, Sohleifer, and Vishny (1999) in a paper published by the American National Bureau of Economic Research. They conclude that multicultural societies are less well governed and have poorer economic performance than ethnically and racially homogenous societies because the competing ethnic and racial groups expend too much of their energy and resources in trying to advance the interests of their own groups.
Fourth, the genetic cost of much of the immigration into the Western democracies in the second half of the twentieth century has arisen from the acceptances of large numbers of immigrants with low intelligence and a high propensity to crime. In the United States these problems have been present among Hispanics and blacks, as shown by Herrnstein and Murray (1994) and in many other studies. In Britain also, immigrants from sub-Saharan Africa have manifested the same characteristics as blacks in the United States—low intelligence, poor educational attainment, high unemployment, high welfare dependency, and a crime rate approximately six times greater than that of the indigenous population (Mackintosh & Mascie-Taylor, 1984; Tonry, 1997). These characteristics have some genetic basis, and the acceptance of these immigrants has imposed a genetic cost on the population, both for present and future generations.
