And, of course, people aren't going to stop wanting to get drunk just because they can't pop over to the corner bodega for a six pack whenever the urge strikes. Portability and long shelf-life make liquor of all types a valuable trade good -- people will kill to get a taste of the delicious bottom-shelf leftovers from your local dive bar when their only other option is the equivalent of prison wine.
Survivalists' concerns and preparations have changed over the years. During the 1970s, fears were economic collapse, hyperinflation, and famine. Preparations included food storage and survival retreats in the country which could be farmed. Some survivalists stockpiled precious metals and barterable goods (such as common-caliber ammunition) because they assumed that paper currency would become worthless. During the early 1980s, nuclear war became a common fear, and some survivalists constructed fallout shelters.
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.
When bands of marauders start roaming the streets, how are you going to keep them out? Tear down a few walls, says Timothy Ferraro, a twenty-five-year construction veteran who's thought about this situation plenty while watching The Walking Dead. "Assuming the attackers don't have a battering ram, you should be able to keep them out using the lumber and drywall already in your home," he says.
