Over the past few decades, American society has been transformed in a fit of absence of mind. First, we’ve gone from a low immigrant nation to a high immigrant nation. If you grew up between 1950 and 1985, you grew up at a time when only about 5 percent or 6 percent of American residents were foreign born. Today, roughly 13 percent of American residents are foreign born, and we’re possibly heading to 15 percent.

Moreover, up until now, America was primarily an outpost of European civilization. Between 1830 and 1880, 80 percent of the immigrants came from Northern and Western Europe. Over the following decades, the bulk came from Southern and Central Europe. In 1960, 75 percent of the foreign-born population came from Europe, with European ideas and European heritage.

Soon, we will no longer be an outpost of Europe, but a nation of mutts, a nation with hundreds of fluid ethnicities from around the world, intermarrying and intermingling. Americans of European descent are already a minority among 5-year-olds. European-Americans will be a minority over all in 30 years at the latest, and probably sooner.

If enacted, the immigration reform bill would accelerate these trends. It would further increase immigration levels. According to the Census Bureau, roughly 20 million immigrants will come to this country under current law. The Congressional Budget Office expects another 16 million under the new provisions.
