Besides taking jobs from American workers, illegal immigration creates huge economic burdens on our health care system, our education system, our criminal justice system, our environment, our infrastructure and our public safety.

Technology and robotics are advancing and will reduce the need for workers in the future.

If cheap immigrant labor is made unavailable, employers can hire Americans at a higher wage, or replace low-wage immigrant workers with technology and automation, which will create a smaller number of skilled jobs for Americans.
