The U.S. immigration debate: what’s all the shouting for?

Potential GDP growth has slowed by 1.3% a year. The main culprit is labor force decline. It follows logically that a more welcoming immigration policy would be responsive to our demographic challenges and thereby complementary to macroeconomic growth. Ironically, anger at immigration has grown in inverse proportion to actual immigration flows. There is little evidence that immigrants have negative impacts on the wages of native-born workers, and increased immigration would likely have a net positive fiscal impact. Based on these economic considerations, the U.S. immigration debate seems driven by much more heat than light.
