> once you start starving you should certainly consider working again Free-rider problem, and the black (or gray) market. If all the value I capture from working is one/population of the value I produce, there are probably other things I can do (in an environment with a population bigger than "really small village") that will do substantially more to improve my circumstances, whether legal or not (and some things are bound to be legal - consider a kind of analog of the "man who marries his housekeeper" objection to GDP). And when people are desperate, they are more likely to focus on the things that will most improve their circumstance (especially in the shortest term).
