Watching the footage of the bridge collapse in Minneapolis, I couldn't help but think: why do the folks being interviewed in this city look and sound so different from those interviewed in New Orleans two years ago? Granted, the scale of the calamities are different, but even so, how can we pretend that these two cities are even in the same "America"? At times like this, this country seems more a concept than a place with any cultural or social coherence. And is this one of the things that makes America interesting and sort of cool, or is it a scandal? Would we erase these differences if we could, seeing that the differences are so great? Not a rhetorical question.
