Inequality, an issue politicians talked about hesitantly, if at all, a decade ago, is now a central focus of candidates in both parties. The terms of the debate, however, are about individuals and classes: the elite versus the middle, the 1 percent versus the 99 percent. That's fair enough. But the language currently used to describe inequality doesn't capture the way it is manifesting geographically. Growing inequality between and among regions and metro areas is obvious. But it is almost completely absent from the current political conversation.
