This was required reading for grad school. Unfortunately, even though this is the second edition, it's outdated already, just 6 years from the date of publication. Even so, Carroll has some good thoughts in here, and does some excellent critical thinking about immigration, and presents "the other side" of the argument quite fairly (a little too fairly for my taste; he presents racists and xenophobes as if they have valid points, when they absolutely do not). I'd be really interested to hear Carroll speak today or even to read a third edition of this book in response to the Trump era. In 2013 Carroll had a LOT of optimism about the possibilities for immigration reform in the United States. I imagine much of that optimism has been lost since the 2016 election.
