There seems to be standard story that runs on a lot of survivalist material. Something catastrophic will occur. The unwashed, clueless masses will immediately turn to rioting and looting, while the valiant, prepared will be safe in their fortified bug out locations.

Let's just say this is a bit simplified and is not borne out by the history of past disasters as they have unfolded. This is not to say that looting,etc. go away in bad times, but society doesn't usually collapse into total chaos.

Ian's mention of the blitz in WWII is a good example of toughness in the face of adversity.
