This, of course, is entirely consistent with the consensus among U.S. labor economists - immigration brings no net aggregate gain to the native-born - that I noted in Alien Nation almost exactly thirteen years ago. (P. 163-164 noted similar results from Canada and Australia).
Three years earlier, in the National Review cover story that grew into Alien Nation, I quoted George Borjas making the same point: ("The economic arguments for immigration simply aren't decisive. You have to make a political case...")
Why has this simple point still not penetrated public consciousness? Because that would required campaigning journalism - endless anecdotes embroidering same moral. Needless to say, I blame Bill Buckley.
