When you think about it, in all of the natural and man-made disasters that have occurred in the United States in the last, oh, 25 years or so, those impacted most directly have for the most part been able to survive the aftermaths. Yes, there was some looting in some cases, and desperate (though not fatal) circumstances due to lack of power and shortages of food and medicine and so forth -- but really, very few people have ever died as a result of the temporary "collapse of society" in the United States to use that term very loosely. We are a modern democratic society, the richest nation in the world, and we are a nation that reaches out to help those who have experienced these tragedies. I don't think that's going to change; it's part of who we are.
Doesn't mean some epic, huge catastrophe on a national or international scale couldn't happen, or won't. (The Bible says that it will, and I believe that, and am trying to make the necessary preparations to "survive" that one.

) But I would just encourage anyone who fears total collapse to remember that it has never happened, and that if it ever does, surviving long-term in the aftermath probably won't really be worth it. So instead of devoting so much time and resources to preparing for it, why not work in the here and now to make things better for yourself and, especially, other people?
Tomorrow is never promised anyway; only the strength for today. So live and do your best in this moment, which is the one that matters.
Just my opinion.
