I'd point out that the UK's GDP growth predictions... even lowered actually aren't that far off the US.
EVERYWHERE regardless of strategy seems to be stuck at ~1-2% GDP growth.
Even if you think the debt spending is making the difference... why kill yourself for 2%, building up a future huge disaster? When you could have 1% and have a safer future?
Espiecally if nearly all that 1% is a boost soley due to government spending!
