Dangerous professions like construction have cultural and political effects of their own which are generated out of material conditions on the ground.
In dangerous and stressful situations, which involve dangerous materials and objects, and economic pressures which encourage unconditional competence and speed, there emerges an environment of aggression between workers in cooperation.
In stressful situations, being yelled at and appealed to with urgency tends to pump adrenaline and trigger a fight or flight reflex, which is not always great for processes which require skill and concentration, and which in the untrained individual, only bring forth confusion and hesitation, while in others it elicits reckless and aggressive action. This kind of behavior tends to elicit more yelling, frustration, and aggression, which in turn pumps more adrenaline, and etc.
These are situations which are bound to happen through the course of living. Sometimes we are threatened as a group, and stress runs its course through the group as it will.
But with our extreme division of labor, the bulk of this occurrence is concentrated on given professions, and takes the form of a daily pressure on whoever enters into this given division. It is a pressure which is constant and dramatic enough to actually influence and form the affected individual, who then enters fully formed into the greater culture and interacts with other individuals.
And through this constant pressure, and this constant wear, there emerges a resent and a sense of entitlement developed in the face of risk and daily hardship. The divisions of labor form different types of people, with differently concentrated human natures which then proceed to crash with each other.
