interesting article on immigration

I came across an eye-opening article on the "immigration" issue. Very well written to cover the complexities of the issue.

I have often felt that mainstream discussions on the topic do not delve into the issue deeply enough (then again, most people don't discuss, they just state their opinions), and the proposed "solutions" are weak and short-sighted. This article is a breath of fresh air and says things I have felt but didn't have the words to express.
