1. A Darwin Trap is an obvious -hazard with appropriate signage -that can be avoided easily, causing no harm or inconvenience and yet somehow, some poor idiot inevitably gets trapped, hurt, killed, or maimed by the aforementioned obstacle, complementing Darwin's theory of evolution "only the strong survive"
2. A social economic state in which Business needs constant constant growth to appease stockholders, which inevitably screws up the economy because there is only so much business market to go around.
A manhole with no cover surrounded by barricades, flashing lights, and danger signs indicating there is a danger, an obvious Darwin Trap. Well cautioned Idiot gets stuck, hurt or killed from entering the "no fly zone", usually making the local 8'oclock news.
