Illegal immigrants don't take jobs away from American workers

Eduardo Porter in Immigration and American Jobs:

[Economists] confirm earlier findings that immigration on the whole has not led to fewer jobs for American workers. More significantly, they suggest that immigrants have had, at most, a small negative impact on the wages of Americans who compete with them most directly, those with a high school degree or less.

Meanwhile, the research has found that immigrants – including the poor, uneducated ones coming from south of the border — have a big positive impact on the economy over the long run, bolstering the profitability of American firms, reducing the prices of some products and services by providing employers with a new labor source and creating more opportunities for investment and jobs.
