But what if it doesn't know it's dead?

Richard Eskow's history of austerity economics  over the past couple of years (read the whole thing!) claims that that zombie theory is dead, defunct, no longer with us:

The name of the deceased was "Austerity Economics," and it was first glimpsed in a 1921 paper by conservative economist Frank Wright. Austerity died of natural causes brought on by prolonged exposure to reality.

But the thing about zombies is--well, you know what the thing about zombies is. They're dead already. According to Wikipedia, what you need to do is feed them with salt. Any ideas?
