I'm not sure that we disagree. The person I was responding to was framing things in terms of how US immigration policy benefits people who are not US citizens. I was just pointing out that the US government is morally obligated to attend primarily to the interests of it's own citizens (IMO; I realize this is a controversial opinion in some circles). I tend to take a pretty expansive position on what constitutes the best interests of US citizens and generally think it's good for the US that most countries have significant expat populations in the US.
