Stephen Colbert on the subject of migrant workers:

I like talking about people who don’t have any power, and it seems like one of the least powerful people in the United States are migrant workers who come in and do our work, but don’t have any rights as a result. And yet, we still ask them to come here, and at the same time, ask them to leave. And that’s an interesting contradiction to me, and um… You know, “whatsoever you did for the least of my brothers,” and these seemed like the least of our brothers, right now. A lot of people are “least brothers” right now, with the economy so hard, and I don’t want to take anyone’s hardship away from them or diminish it or anything like that. But migrant workers suffer, and have no rights.

— Stephen Colbert, briefly out of character in his testimony before congress.

Update: Washington Post columnist Ezra Klein has a post arguing why immigration is not only a religious and moral issue, but a practical issue for the good of the country. I had trouble following the chart, and would recommend skipping straight to the post proper.
