>>5311444anyone 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. The typical high school dropout earns about $25,000 annually. According to census data, immigrants admitted in the past two decades lacking a high school diploma have increased the size of the low-skilled workforce by roughly 25 percent. As a result, the earnings of this particularly vulnerable group dropped by between $800 and $1,500 each year.
