You are not acknowledging the fact that there is competition and there is also cooperation in business. Nothing would prevent businesses from making deals that make sense for both parties, as far as sharing already established infrastructure.
How do you feel about the unilateral "forgiveness" of illegal immigrants for political gain? In California, not only are federal immigration laws unenforced, people are issued driver licenses. The mind boggles. I know of no other country that would do something so insane. If you are narrowly focused on "jobs", this should be an issue.
