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?
