Jacoby answers that less and less Americans are available to take low-skilled jobs, and these need to be filled by immigrants. It doesn't make sense to pay Americans for jobs they are overqualified for. Briggs and Krikorian respond that there is no such thing as jobs that will not be taken by American workers. Markets will always adapt to the type of workers available, but having illegal labor available will be detrimental to U.S. workers. Medina counters that if undocumented workers had legal status, employers would not be able to take advantage of them.
