Interrupting the scheduled blog post about Rust Belt immigration, Richard Longworth spoke at the University of Illinois at Springfield and there is video of his talk. When I find some time to watch it, I'll provide some commentary on what he said.
Edit: I watched the video, which is very short and offers just a few sound bytes from Dick's talk. The clip does capture his overall message. The Midwest is failing to deal with globalization and something has to change.
