At least some–certainly not all–of the recent debate over immigration focuses on the economic impact.  Writing at Slate, Daniel Gross looks at a new BLS study that pulls the available data together.  Here’s an interesting clip:

Not all immigrants are uneducated, low-skilled workers—not by a long shot. The BLS notes that “about equal proportions of both the foreign and native-born had a bachelor’s degree and higher, 31 and 33, respectively.” And the workers who arrived here with college degrees—or obtained degrees after they arrived—have narrowed the earnings gap with native-borns rather quickly. As Table 5 shows, the weekly median earnings for foreign-born workers who have a bachelor’s degree (there are 4.553 million of them) are about 94 percent of those from similarly educated native-born workers.
