15% of the U. S. labor force is foreign-born.
Immigrant workers account for 36% of all labor without a high school diploma.
Immigrant workers account for 41% of scientists with doctoral degrees.
Immigrants earn 77 cents for every 1 dollar earned by native workers, though this gap almost evaporates for those with college degrees.
Over 90% of native workers benefit from the influx of low-wage immigrants because these workers take jobs that complement the work of higher paid native workers. For example, immigrants who work in the roofing business lower costs for contractors and home builders, who create jobs for plumbers, electricians and others, while lowering the prices for houses that benefit consumers.
Some native workers who compete directly with immigrants may suffer in certain, unskilled labor areas, but not as much as they do thanks to other factors, such as technological advances, globalization and minimum wage levels.
Final thought regarding the impact of immigrants on our nation's workforce:
"There's this aversion to immigration, but people should be much more averse to computers. They are much more responsible for the bad effects."
