Here comes the choo-choo train...

And from the BBC right on time, we have World growth to 'resist US blip'.

The global economy should be able to withstand a slowdown in the US and wobbles in its housing market, the International Monetary Fund (IMF) says.

However, the IMF said that the problems were US specific and should not spread.

"Most countries should be in a position to decouple from the US economy and sustain strong growth if the US slowdown remains moderate as expected," the IMF said in its World Economic Outlook report.

Ah, yes! The "decoupling" hypothesis.

Let's review the progression of events:

There is no problem.

There is a problem but it will be contained within subprime.

There is a problem but the US slowdown will be moderate.

There will be a 'US blip' but the world will decouple.

So when the US is rockin' and rollin', the global economy is the beneficiary, but when the shit hits the fan, they will decouple?

Chuffa, Puffa, Chuffa, Puffa! The bullshit train's right on time.
