1st -- realize that this is a contributed editorial from Robert Scrivner @ Harvard... Also, just because wages may not be seemingly impacted... Their study doesn't seem to factor this in...

First you state that we must realize it is from this particular Professor, and second that you nickpick aspects of his study. Sounds like Prof. Borgas sadly lacks max-rpf's unique economic analysis abilities.
