Our reading
An editorial interpretation.
The speaker wryly laments that demons now chase money, missing the old grisly tradition of ritual sacrifice, the still-beating heart of a virgin. The complaint treats monstrous ritual as a standard that has slipped, so ordinary greed reads as a disappointing lack of ambition.
