The new jobs numbers show that the civilian labor force has shrunk over the past year by 2 million people — that’s 2 million people who didn’t just lose their jobs but who stopped looking altogether. And over that same year, we let in — legally — well over a million working-age foreigners, both immigrants and “temporary” workers. And assuming that a large share of those foreign workers got jobs, that means well over 2 million Americans and earlier immigrants dropped out of the labor market. (And it’s a good bet that the new immigrants have jobs, since during 2000-2010, all of the net job growth — 100 percent — went to immigrants.)

So, can someone explain why we’re taking any new immigrants and why we’re not opening up jobs through aggressive worksite enforcement of immigration laws?
