All this junior Boy Scout stuff about being prepared and having full stocks of food ,water,Evian, guns and ammo and how tough everyone is probably serves some kind of group psychological need. You guys must think you are somehow better people for advising the unfortunates who "stayed behind" and were victimized by alleged roving bands of criminals.
As the truth slowly unwinds, the "unfotunates" are people you may have never encountered, who are truly without resources of practically any kind. The truly hopeless, down and out as well as mentally challenged without so much as bus fare are the types being described. People without jobs,money,or means to the point that advising them to have a months worth of food is utterly ridiculous. These are the pitifully "without" underclass who may eventually recieve pity from caring adults.
Brutal reality will make your little "helpful hints" shake and bake seem even more silly than it already is to begin with.
