"U.S. immigration policy has a beneficent intent. However, recent work suggests that the signal it sends internationally--that emigration can be relied upon to relieve local (Third World) population pressure--tends to maintain high fertility rates in the sending country. This effect is counterproductive because high fertility is the primary driver of rapid population growth. In addition, it appears that the relatively open U.S. immigration policy has resulted in a rate of domestic population growth that threatens both the well-being of American labor and cherished environmental values."
