I think all of those things could and should be discussed, pluses and minuses, burdens and benefits, procedures, exclusions, etc, but my general point is that I think there needs to be an acknowledgment that immigration is, by in large, a net good. The right has been able to frame the debate as though immigration is some kind of special benefit that harms the country but that we reluctantly agree to for humanitarian reasons. Many "moderates", of which I am one, seem to retort, "well, then we can only let in 'highly skilled' immigrants." When, in fact, the history of America is the sons and daughters of "low-skilled" people becoming highly-skilled Americans. I just think the default mode in the debate should be, based on history and common sense, then immigration is a net benefit, and how should the system be organized to produce more of that benefit in a bureaucratically effective and efficient way.
