It will be a legitimate value when employers who abuse the presence of undocumented immigrants are held criminally accountable, and/or when legislators take action, per bipartisan request, to legalize the de facto state of immigration in the Americas, of whatever character and magnitude that social stability can afford. Until then, it's just xenophobia and racism, and especially egregious because a good number of "immigrants" are the descendants of people who've lived on and migrated around this continent for 10,000+ years.
