Recent employment gains by immigrants did not lead to declines among native-born Americans, visiting fellow Harry Holzer pointed out in testimony before the House Judiciary Subcommittee on Immigration, Border Security and Claims. Over the long term, immigration has modest negative effects on less-educated workers but other positive effects on the economy--and the plus side will grow much stronger after baby boomers retire. Workers are thus best served by policies that stimulate job growth in the short term, and their own skills and incomes over the long term, rather than by policies that curb immigration drastically.
