In the same vein some claim that miners were more socialist and fishermen more religious. Reason being that a miner's output is proportional to how much ore they mine, while a fisherman needs to get lucky to haul in a good catch. This was before industrial fishing. Hard to know if there is any truth to this or if it's all folklore. But perhaps this sort of thinking can explain why developers tend to be hyper-individualists -- most of their work (ie bug-fixing) is caused by other people screwing up.
