“[A]nyone who tells you that immigration doesn’t have any negative effects doesn’t understand how it really works. When the supply of workers goes up, the price that firms have to pay to hire workers goes down. Wage trends over the past half-century suggest that a 10 percent increase in the number of workers with a particular set of skills probably lowers the wage of that group by at least 3 percent. Even after the economy has fully adjusted, those skill groups that received the most immigrants will still offer lower pay relative to those that received fewer immigrants.
Both low- and high-skilled natives are affected by the influx of immigrants. But because a disproportionate percentage of immigrants have few skills, it is low-skilled American workers, including many blacks and Hispanics, who have suffered most from this wage dip. The monetary loss is sizable…
We don’t need to rely on complex statistical calculations to see the harm being done to some workers. Simply look at how employers have reacted.

Shortly after, Crider placed an ad in the local newspaper announcing job openings at higher wages.”Sep./Oct. 2016
