Sabastian Mallaby, Council on Foreign Relations, makes a persuasive case against nativist nonsense in his Washington Post column: "People say that immigrants steal jobs from native-born Americans. But economists have patiently explained for years that there is no finite 'lump of labor' in an economy. The presence of migrants causes new jobs to be created: Factories that might have gone abroad spring up in Arizona or Texas. Hasn't anyone noticed that California, where fully one-third of the adult population is foreign born, has an unemployment rate of less than 5 percent?"
"People say that immigrants cause wage losses even if they don't cause job losses. Here the story is subtle: Some studies find no evidence that immigrants pull down wages, while others find that native-born high school dropouts lost as much as 9 percent of their earnings between 1980 and 2000 as a result of immigration. But -- and here comes the sane scream -- there's no way that even a 9 percent wage loss can justify the policies that immigration hawks advocate." Read the whole thing.
