The article says that immigrants are good for economic growth. What good is economic growth good for? I already have 5 smartphones! (and five desktop/latpop computers). What good will it do to have MORE? Yes, immigrants are bad, because our societies are reaching a point where we have to evolve not toward more but toward better, and this means not necessarily more people (while I'm quite critical about abortion, I don't consider that some demographic reduction to be bad, unless you're considering competiting demographic pressure, if we cannot contain it otherwise than with some demographic pressure of our own, which really sounds silly given the ecologic impact and resources available otherwise).
