I live near Mt. Rushmore. When my mom was a kid, working there during tourist season was a very common summer job for high school kids. Now it's not, because now temporary foreign labor by means of seasonal visa programs, complete with housing, fills those jobs each summer instead. Are American high schoolers physically/mentally unable to do these jobs? Of course not—yet these job opportunities have been taken from them regardless, replaced with what is essentially seasonal foreign-labor indentured servitude.
