Breaking the silence on immigration

But critics point out that some immigrants are taking jobs from native citizens. Here in the US, for example, the number of foreign-born adults holding a job has grown by 1.7 million since 2000, while the number of working native-born Americans has fallen by 800,000, points out Steven Camarota, research director at the Center for Immigration Studies in Washington.

Estimates of total immigration to the US vary. Mr. Camarota figures it's running at 1.2 million to 1.3 million a year on a net basis (taking account of those who have died or gone back home). The Federation for American Immigration Reform (FAIR), another Washington group interested in restraining immigration, pegs the number a bit higher - a net 1.4 million. That's well above the 1.13 million average annual inflow during the 1990s.

By 2050, immigration will boost the US population to 420 million, up from 292 million now, according to census projections. Jack Martin, project director at FAIR, reckons it could reach close to 500 million. "It's a staggering amount of people," he says.

Americans worry about that rising tide. Poll after poll shows they want less immigration and the immigration laws properly enforced. Last month, for instance, the Pew Research Center for the People and the Press found that 77 percent of those polled agreed that "we should restrict and control people coming into the country to live more than we do now." A June Gallup poll found 47 percent want immigration decreased and only 13 percent want it increased.

But action on immigration can be politically risky. Ethnic groups, such as Hispanics, may cast their votes against a politician seeking to restrain immigration or limit benefits to illegal immigrants.

Before the recall vote in California, Gov. Gray Davis switched positions and signed a bill that would have allowed illegal immigrants to use a tax identification number to get a driver's license. It was an appeal to Latino voters.

On Monday, the state legislature repealed the law.

In Washington, reluctance stems from "the elites who control 90 percent of the jobs in the country and are more interested in pursuing a short-term greed agenda," says Dan Stein, executive director of FAIR. He says powerful interests such as the meat-packing industry, home builders, restaurants and hotels, landscape firms, and the farmers who employ immigrants to pick their crops want to keep labor costs low by hiring immigrants.

Many academics agree that heavy immigration does dampen wages for the unskilled. Lisa Catanzarite, a sociologist at the University of California, finds that in occupations where new Hispanic immigrants account for a quarter of the work force, the jobs pay up to 11 percent less than those where there are no new Latino immigrant men.

And economists figure that immigrants help push up home prices in many cities in the nation.

Should the US worry about the rising tide of people?

"The numbers will be manageable," says Kelley. "Immigration is the genius of America. Immigrants change America, and Americans change them." Further, she argues, the aging of the American population means more immigrants will be needed to do the work.

Not everyone agrees. With less immigration, wages may rise for lower-skilled workers, says Dean Baker, an economist with the Center for Economic and Policy Research in Washington. Thus, some less important jobs may disappear - the midnight shift at the convenience store, for instance. Or teenagers may rake leaves - not Hispanic immigrants.
