In private Facebook groups, wealthy survivalists swap tips on gas masks, bunkers, and locations safe from the effects of climate change. One member, the head of an investment firm, told me, “I keep a helicopter gassed up all the time, and I have an underground bunker with an air-filtration system.” He said that his preparations probably put him at the “extreme” end among his peers. But he added, “A lot of my friends do the guns and the motorcycles and the gold coins. That’s not too rare anymore.”
Tim Chang, a forty-four-year-old managing director at Mayfield Fund, a venture-capital firm, told me, “There’s a bunch of us in the Valley. We meet up and have these financial-hacking dinners and talk about backup plans people are doing. It runs the gamut from a lot of people stocking up on Bitcoin and cryptocurrency, to figuring out how to get second passports if they need it, to having vacation homes in other countries that could be escape havens.” He said, “I’ll be candid: I’m stockpiling now on real estate to generate passive income but also to have havens to go to.” He and his wife, who is in technology, keep a set of bags packed for themselves and their four-year-old daughter. He told me, “I kind of have this terror scenario: ‘Oh, my God, if there is a civil war or a giant earthquake that cleaves off part of California, we want to be ready.’ ”
