In an attempt to justify more Keynesian stimulus spending, Paul Krugman has suggested a strategy which has now most cleverly been dubbed Wag the Dalek - yes, a fake invasion by space aliens to justify massive government spending.
Actually, given the consistent Keynesian failure to understand that every dollar the government spends is a dollar not being spent by taxpayers themselves, I'm a little disappointed that Krugman didn't advocate a real alien invasion. Imagine the jobs created rebuilding our civilization once those helpful aliens blast us back to the stone age with their death rays.
It's all too bizarre for words. I do see the work of aliens here, but what I really think has happened is that the Nobel prize winning economist we called Paul Krugman has been replaced by an alien pretending (not very well) to be Paul Krugman. Seriously. How else can you explain this guy seeming to have unlearnt everything he ever knew as an economist?
Update: You can buy a (slightly geeky) t-shirt that makes the point:
