That's not an incentive at all; they're much more likely to just buy bunkers:

When Marvin Liao, a former Yahoo executive who is now a partner at 500 Startups, a venture-capital firm, considered his preparations, he decided that his caches of water and food were not enough. “What if someone comes and takes this?” he asked me. To protect his wife and daughter, he said, “I don’t have guns, but I have a lot of other weaponry. I took classes in archery.”

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.”

Steve Huffman, the thirty-three-year-old co-founder and C.E.O. of Reddit, which is valued at six hundred million dollars, was nearsighted until November, 2015, when he arranged to have laser eye surgery. He underwent the procedure not for the sake of convenience or appearance but, rather, for a reason he doesn’t usually talk much about: he hopes that it will improve his odds of surviving a disaster, whether natural or man-made. “If the world ends—and not even if the world ends, but if we have trouble—getting contacts or glasses is going to be a huge pain in the ass,” he told me recently. “Without them, I’m fucked.”

Huffman, who lives in San Francisco, has large blue eyes, thick, sandy hair, and an air of restless curiosity; at the University of Virginia, he was a competitive ballroom dancer, who hacked his roommate’s Web site as a prank. He is less focussed on a specific threat—a quake on the San Andreas, a pandemic, a dirty bomb—than he is on the aftermath, “the temporary collapse of our government and structures,” as he puts it. “I own a couple of motorcycles. I have a bunch of guns and ammo. Food. I figure that, with that, I can hole up in my house for some amount of time.”

Huffman has been a frequent attendee at Burning Man, the annual, clothing-optional festival in the Nevada desert, where artists mingle with moguls. He fell in love with one of its core principles, “radical self-reliance,” which he takes to mean “happy to help others, but not wanting to require others.” (Among survivalists, or “preppers,” as some call themselves, FEMA, the Federal Emergency Management Agency, stands for “Foolishly Expecting Meaningful Aid.”) Huffman has calculated that, in the event of a disaster, he would seek out some form of community: “Being around other people is a good thing. I also have this somewhat egotistical view that I’m a pretty good leader. I will probably be in charge, or at least not a slave, when push comes to shove.”

Why would they care if people were pissed off when they can afford not to care? Especially with enough Chinese and Saudi blood money that they could blow their noses with tissues made of hundred-dollar bills? They're above your problems, they're above everyone else's.
