Here is Mark Helprin on the immigration debate, and the coming together of political opposites. A left that disdains America and a business right both is "similar to the self-satisfaction of those who would have sold Lenin the rope with which he planned to hang them. This is the lobby, strange as it may seem, for illegal immigration." The importation of labor, he asserts, is the essence of the illegal immigration question.
Update: You had also better read Mark Steyn on why this is really NOT an illegal immigration issue at all.
