This group has a primary concern with maintaining some form of legal system and social cohesion after a breakdown in the technical infrastructure of society. They are interested in works like The Postman by David Brin, Lewis Dartnell's The Knowledge: How to Rebuild Our World from Scratch, or Marcus B. Hatfield's The American Common Law: The Customary Law of the American Nation.
There are some weight considerations in that MREs weigh more than freeze dried food but they do have their advantages. I have a few boxes stored as part of my food storage plan because they are an easy way to get the calories you need for survival. I also have food stored in buckets, canned food and freeze-dried food. I am an equal opportunity food storage person and there is something to be said for having variety. Are MREs the the best prepper food? I don’t think there is ever a single best food for all prepper situations, but MREs are proven reliable. If our military uses them you can bet that you could find reasons to use them too. They are more expensive than other options but you don’t have to prepare anything, they even throw in the salt, pepper and a little moist towelette to wipe your face and hands when you are done. They used to come with toilet paper and chewing gum but apparently that is not part of these MREs.
Still, these extraterrestrial-looking foodstuffs seem to be having something of a moment: For the past four years, Costco has been selling pallets of shriveled vegetables, fruits, grains, and meats that promise to feed a single family for up to a year—and if you’re not a member, you can purchase similar survival kits, many of which boast a 20- to 30-year shelf life, at Walmart and Target. One top seller, Wise Company, saw its sales nearly double over the past four years, reaching around $75 million, according to a Bloomberg Businessweek cover story last November. The company’s CEO, Jack Shields, told me he estimates the industry as a whole generates between $400 and $450 million annually in retail.
