I mean, how wrong was he? In hindsight we know that he underestimated the slowdown and how the economy will "behave". But in 2007 March, when he delivered that statement, was he in accordance with best practices, best models about economics, and was he communicating about the data, indicators, possibilities, models and all that in the best way (known at the time to be the most optimal)? I'm not trying to "whitewash" him, but this whole piece is just about being very truthful, maximally correct with regards to economics. Look at the data and just the data, not your wishes. But then it seems that's not happening when it comes to its first economics related example.
