Nostalgia, Immigration and Inequality

I'm not a big fan of Brink Lindsey, but his article on nostalgia economics in Reason is worth reading.

A sample

Under the system that existed between 1924 and 1965, immigration quotas were set for each country based on the percentage of people with that national origin already living in the U.S. (with immigration from East and South Asia banned outright until 1952). The explicit purpose of the national-origin quotas was to freeze the ethnic composition of the United States—that is, to preserve white Protestant supremacy and protect the country from “undesirable” races. “Unquestionably, there are fine human beings in all parts of the world,” Sen. Robert Byrd (D-W.V.) said in defense of the quota system in 1965, “but people do differ widely in their social habits, their levels of ambition, their mechanical aptitudes, their inherited ability and intelligence, their moral traditions, and their capacity for maintaining stable governments.”

But the times had passed the former Klansman by. With the triumph of the civil rights movement, official discrimination based on national origin was no longer sustainable. Just two months after signing the Voting Rights Act, President Lyndon Johnson signed the Immigration and Nationality Act of 1965, ending the “un-American” system of national-origin quotas and its “twin barriers of prejudice and privilege.” The act inaugurated a new era of mass immigration: Foreign-born residents of the United States have surged from 5 percent of the population in 1970 to 12.5 percent as of 2006.

This wave of immigration exerted a mild downward pressure on the wages of native-born low-skilled workers, with most estimates showing a small effect. Immigration’s more dramatic impact on measurements of inequality has come by increasing the number of less-skilled workers, thereby increasing apparent inequality by depressing average wages at the low end of the income distribution. According to the American University economist Robert Lerman, excluding recent immigrants from the analysis would eliminate roughly 30 percent of the increase in adult male annual earnings inequality between 1979 and 1996.

Although the large influx of unskilled immigrants has made American inequality statistics look worse, it has actually reduced inequality for the people involved. After all, immigrants experience large wage gains as a result of relocating to the United States, thereby reducing the cumulative wage gap between them and top earners in this country. When Lerman recalculated trends in inequality to include, at the beginning of the period, recent immigrants and their native-country wages, he found equality had increased rather than decreased. Immigration has increased inequality at home but decreased it on a global scale.
