I would say that the Southern Senators who have made this mess are trying to set up a regional monopoly on auto manufacture, and there’s no reason to believe they will succeed in doing anything but making a lot of people miserable; the time for regional monopolies seems to have ended. (Krugman pointed out that the time for regional monopolies in the auto industry seems to have ended at the end of his Nobel lecture, and was immediately misquoted. Go listen to it—-there’s no transcription yet.)
It turns out, by the way, that my call is more properly transcribed as "krawk" or "croak". Krawk!
