Ezra Klein has a seriously researched piece in the Post on why the stimulus was inadequate and what else could have been done. The major item missing in my book is any discussion of the overselling of the stimulus after its passage.
By all accounts, Obama's economic team knew that the stimulus they got through Congress was inadequate for the task. They needed a stimulus that was at least twice as large as what Congress passed and quite possibly three or four times as large. Nonetheless, President Obama was quickly running around touting the "green shoots of recovery" and talking about the need to focus on deficit reduction.
By overselling the stimulus and putting deficit reduction at the top of the agenda, Obama was virtually shutting the door on the possibility of getting further stimulus. Since they knew that additional stimulus would almost certainly be necessary, why did they dig themselves into this hole?
It would be interesting to some explanation of this situation. Nonetheless, the piece is well worth reading. The Post deserves some credit for running it.
