On immigration, the evidence is overwhelming; the best way forward is clear.

The forlorn pundit doesn’t even have to make the humanitarian case that immigration reform would be a great victory for human dignity. The cold economic case by itself is so strong.

Increased immigration would boost the U.S. economy. Immigrants are 30 percent more likely to start new businesses than native-born Americans, according to a research summary by Michael Greenstone and Adam Looney of The Hamilton Project. They are more likely to earn patents. A quarter of new high-tech companies with more than $1 million in sales were also founded by the foreign-born.

A study by Madeline Zavodny, an economics professor at Agnes Scott College, found that every additional 100 foreign-born workers in science and technology fields is associated with 262 additional jobs for U.S. natives.
