The illegal immigration movement is not just about economic issues, although those are huge; nor is it confined to job issues. The social welfare costs are enormous; in California, for example, they are well north of $10 billion a year, probably more like $15 billion.
Then there's the touchy issue of cultural fragmentation and how that impinges on the political and social values we have taken for granted in this nation for a long time. Our idea of a democratic republic is not one shared by many outside a specific geographic locus; it is an uncomfortable truth but one we need to think hard about regardless of the fact that it's politically incorrect.
