This debate is meaningless unless a definition of "justice" is provided. In the context of this article it appears to mean that all foreigners should have the right to enter any country, enjoy the benefits provided by that country's laws on an equal basis with its current citizens, displace them in the work force and universities, and reduce their standard of living by redistributing wealth. If that is the meaning of "justice", then no country is "just".
