I think that can be attributed to face-saving politics. That Paulson talked about the US "humiliation" 24 hours previously is IMO a clear sign the group has a pretty solid idea of what happened and how the imbalances need to be redressed. It's just not something that will ever be said in a polite communique like this. As unpleasant as this is going to be for a lot of folks, it would seem the Brits are in for a special form of hell as they may no longer be able to cling to the illusion of "punching above their weight".
The text had to have already been written beforehand because they only met for 6 hours. Guessing they then went thru it section by section "tweaking" for acceptable language and meanings. The biggest thing it says is that they all agreed to pump in fiscal and monetary stimulus while trying to correct the causes. To be honest, I don't see them addressing the imbalances anytime soon, but rather thinking they can gradually change that over time so as to not cause additional crises. Not sure if the debt doesn't blow the lid off in the meantime as it explodes higher. Even if it doesn't, eventually the interest cost will bring about our demise.
