OT:
I haven't anything to say about the repartee between Miller and the reporter. That is what it is. I'm certainly not going to engage in a discussion about a WH pressroom "debate" two other people had.
On the specific topic of immigration in the U.S., there's no denying that George Borjas is the nation's foremost expert on the topic. Accordingly, I will point readers to the summary Borjas published about the net impact of immigration.
I have previously directed readers to that document along with other Borjas immigration studies.
Is the economy larger by a lot as a result of immigration? Not by "a lot," but it is made larger, thus not smaller. In other words, the net impact of immigration is positive. So while one can talk about the various ways in which immigration creates losses, and while another individual can discuss only the benefits, the fact of the matter is that discussing only the losses or only the gains is duplicitous for upon netting the costs and gains, the net result is a gain. Any net outcome is likely to have both costs and gains. The question is whether the costs or gains predominate.
In altering immigration policy, one has three sound tacks from which to choose:
- Alter (sabotage) immigration policy so as to convert immigration's gain into a loss.
- Build upon the gain to make it larger.
Of course, one might also opt to do nothing.
