Council of Economic Advisors, June 20, 2007: Immigration’s Economic Impact: “In 2006, foreign-born workers accounted for 15% of the U.S. labor force, and over the last decade they have accounted for about half of the growth in the labor force. That immigration has fueled U.S. macroeconomic growth is both uncontroversial and unsurprising – more total workers yield more total output. That immigrant workers benefit from working in the United States is also uncontroversial and unsurprising – few would come here otherwise.”
