And some American workers seem to have benefited.
Recently released Census Bureau data from the 2019 American Community Survey (ACS) show that in the first two years of the Trump administration, growth in the immigrant population (legal and illegal) averaged only about 200,000 a year, which stands in stark contrast with the roughly 650,000 a year from 2010 to 2017. The bureau refers to immigrants as “foreign-born,” which includes anyone who was not a U.S. citizen at birth — naturalized citizens, green card holders, long-term temporary visitors, and illegal aliens. It seems almost certain that the slowdown in growth was the result of Trump-administration policies.
One can debate whether this falloff in growth is a positive or negative development, but it is clear that the often-made argument that immigration is like a force of nature, largely driven by economics and outside the control of governmental policy, is false. Although the lower courts have fought the president at every turn, the federal bureaucracy has been resistive, many states have actively subverted the rule of law, and Congress has offered no help, changes adopted by the administration did reduce immigration — both legal and illegal.
