This graph comes from Paul Krugman's latest column for the NY Times in which he takes apart, once and for all, the utter lack of objective reality in the Bush administration's ability to forecast job growth.
Economic forecasting isn't an exact science, but wishful thinking on this scale is unprecedented. Nor can the administration use its all-purpose excuse: all of these forecasts date from after 9/11. What you see in this chart is the signature of a corrupted policy process, in which political propaganda takes the place of professional analysis.
Anyone besides me notice that the slop of each of those gray lines are almost identical? This is yet another indicator of the absolutism of the Bush administration. Object reality no longer matters. What matters is that their theory says jobs will grow at a certain rate and by god that is what they are going to do!
