Trump was also mistaken in his assertion that higher immigration results in lower wages for Americans. In fact, the opposite is true, asQuartz has noted before. In a 2012 study (pdf), economic professors Gianmarco Ottaviano of the London School of Economics and Giovanni Peri of the University of California, Davis, found that immigration in the US between 1990 and 2006 improved the salaries of native-born workers on average by 0.6%. The study also looked specifically at native-born workers with no high school degree, the slice of the US population that is commonly thought of as being most vulnerable to competition from immigrant labor, and found that in their case, too, there was a small, positive impact (between 0.6% and 1.7%) on the wages of native-born workers.
