If they do work, they steal jobs from Americans and increase unemployment. They bring all kinds of diseases with them, and once here they despoil the environment for native-born Americans. To many people, these kinds of statements have the ring of truth. Immigrants use more government services than they pay for with their taxes. Because states provide most services used by immigrants, they can be net financial losers, while the federal government is typically a net gainer.
Immigrants increase unemployment and reduce wages.
In line with a number of other studies, the Cato Institute found that immigrants do not increase joblessness, even among the lowest-paid workers. Other studies have found that immigration either has no effect on wage levels or, at worst, a very slight effect on a very small number of the lowest paid jobs in high-immigrant areas. There is a consensus among business leaders that immigration is vital to maintaining economic growth. Immigrants bring disease. Even though most immigrants come from countries poorer than the United States, recent immigrants are healthier than the U.S.-born population in virtually every particular.
