In eras past, the United States welcomed immigrant laborers to build and support the country's infrastructure and innovators and entrepreneurs to advance its businesses and technology. And yet immigration is a hot-button issue today, with many saying it's a drain on the U.S. economy. Ran Abramitzky, a professor at Stanford University, and Leah Boustan, a professor at Princeton, looked at decades of data to understand the real impact that immigrants and their descendants have on America today. Their findings dispel several modern-day myths and suggest that not just political but also corporate leaders need to push for more rational rhetoric and policies. Abramitzky and Boustan are the authors of "Streets of Gold: America's Untold Story of Immigrant Success."
