We get that creature comforts will be ever more important as the things that used to make us happy slowly break and crumble around us. But do you really want to put a ton of effort into opening a bakery when everything is going to shit? And we hate to be the bearers of bad news, but no amount of odor elimination is going to stop the uncivilized world from smelling really, really bad.
OK. Great. You've stockpiled for the end of the world, you quack. The chances of the world ending are smaller than ... holy crap, what the hell is a supervolcano? See why we're all doomed in 5 Ways The World Could End That You'd Never See Coming. And if that's not enough to get you to build your own bunker, check out 6 Tiny Mistakes That Almost Ended The World. Really, the planet almost ended due to a blown fuse? Come on humanity, let's get it together.

Finelli sits across from me at the food court picnic table inside the Sam’s Club on Sunshine Street, where he requested we meet. The retired computer systems designer-turned–radio show host and homesteader has salt and pepper hair, wears a plaid shirt and jeans and carries a .45-caliber automatic firearm on his person (he won’t say where). Below his strong jawline hangs a leather bag full of crushed sapphire, meant to enhance his overall health. 
Monetary disaster investors believe the Federal Reserve system is fundamentally flawed. Newsletters suggest hard assets of gold and silver bullion, coins, and other precious-metal-oriented investments such as mining shares. Survivalists prepare for paper money to become worthless through hyperinflation. As of late 2009 this is a popular scenario.[37][38][39][40] Many will stockpile bullion in preparation for a market crash that would destroy the value of global currencies.

I asked Hoffman to estimate what share of fellow Silicon Valley billionaires have acquired some level of “apocalypse insurance,” in the form of a hideaway in the U.S. or abroad. “I would guess fifty-plus per cent,” he said, “but that’s parallel with the decision to buy a vacation home. Human motivation is complex, and I think people can say, ‘I now have a safety blanket for this thing that scares me.’ ” The fears vary, but many worry that, as artificial intelligence takes away a growing share of jobs, there will be a backlash against Silicon Valley, America’s second-highest concentration of wealth. (Southwestern Connecticut is first.) “I’ve heard this theme from a bunch of people,” Hoffman said. “Is the country going to turn against the wealthy? Is it going to turn against technological innovation? Is it going to turn into civil disorder?”

Before I headed back to Wichita, we stopped at Hall’s latest project—a second underground complex, in a silo twenty-five miles away. As we pulled up, a crane loomed overhead, hoisting debris from deep below the surface. The complex will contain three times the living space of the original, in part because the garage will be moved to a separate structure. Among other additions, it will have a bowling alley and L.E.D. windows as large as French doors, to create a feeling of openness.

Religion, however, has everything to do with survivalism—there are things about your faith that affect the way you live, Fletch says, offering me an example. “Today, a great deal [on the menu] was the special you had,” he says. “Every one of the specials had pork in it. Well, depending on your belief system and where you’re coming from, Dan, you could’ve made several decisions about me.” He’s right; I could’ve thought he assumed the breakfast was on me, so he ordered the most expensive dish on the menu. And those assumptions, he says, can break up a group. “If 99 percent of the people in your group don’t eat pork, and you bring in some person eating a ham sandwich next to you, that’s going to cause some conflict.” 
If marauding neighbours, starvation and the putrefaction of family members’ corpses wasn’t harrowing enough, the magazine also obsessed over the threat posed by vermin and feral animals that were expected to roam the nuclear wasteland. “A wounded rat can be very dangerous and may attack while you are trying to reload,” explained one article. “If it is necessary to deal with a pack of rats help may be required.”
Articles on the subject appeared in small-distribution libertarian publications such as The Innovator and Atlantis Quarterly. It was during this period that Robert D. Kephart began publishing Inflation Survival Letter[6] (later renamed Personal Finance). For several years the newsletter included a continuing section on personal preparedness written by Stephens. It promoted expensive seminars around the US on similar cautionary topics. Stephens participated, along with James McKeever and other defensive investing, "hard money" advocates.
When I started putting together my first survival kit, I just collected whatever weird stuff I could find—like tablets that would protect my thyroid from nuclear fallout. My mindset changed when my first daughter was born. I realized I needed a more practical end-of-the-world plan, with equipment that would be useful for things that might actually happen. Nuclear war is probably not in store for 2018, and if it is, I’ll just open a window. I don’t want to live through that.
