Let's talk about the fiscal cliff -- you know, the one everyone's all wound up about? Well, the Congressional Budget Office just released their analysis of its potential impact on the economy and it ain't pretty. Add up all the stuff that's scheduled to turn into fiscal pumpkins at midnight on December 31, and you could get a serious impact on the economy. Unemployment would reverse course and start rising if that fiscal scenario remained in place -- but that's a big, important "if." All of the estimates assume we go off the cliff and don't climb back. But if, as Gail Collins imagines it, there's a bungee jump instead of a cliff dive, we can avoid the worst of this. One hopes that Congress can hammer the kind of compromise that has eluded them thus far -- the one that adds tax revenues to any agreement -- before the end of the year, or early next.
