This. Skill sharing among a small tribe is the most effective way to survive a catastrophe, and I am concerned modern societies are poorly conditioned to do it well. Speaking from a North American perspective, kids are educated in how to succeed in a national/global economy, not how to build small communities and develop/share useful skills. TBH, the latter feels "obsolete" nowadays. Maybe that's a problem.
