This article by Steve Sailer was written in 2000, but it could well serve as a response to the optimistic Star article about interracial marriage that I just blogged about. Sailer writes (Continued Immigration Retards Growth of Interracial Marriage, June 8, 2000):
Interracial marriage, however, is not a panacea. As my earlier columns on Latin American intermarriage showed, the Mexicans and Brazilians have been intermarrying for 480 years, but the lightest colored Latins remain firmly in control of their darkest colored countrymen. Nor does intermarriage guarantee in which direction assimilation will occur: for example, the majority of our Anglo-Hispanic families speak Spanish at home. Further, intermarriage has its victims. For example, African-American women and East Asian men have trouble finding spouses because other races tend to find them less sexy than black men or East Asian women.

Nonetheless, intermarriage remains the best hope for melding America's races into one nation. In 20th Century America, intermarriage played a major role in melding WASP's, Italians, Germans, Poles, and Jews into a single white race. What broke down the barriers preventing white ethnics from intermarrying? A host of factors including World Wars and the draft, aggressive government-sponsored assimilation programs, and the rise of self-assertive non-white minorities to remind European-Americans of how small their genetic and cultural differences were relative to racial groups from other continents. One of the most important forces, however, was the great mid-century pause in immigration brought about by the 1924 restrictions. This restricted the inflow of potential marriage partners from the Old Country, encouraging young people to consider people from other white racial groups.
