That's a major reason why average citizens are flocking to survival classes, said Snyder.
"Guys that are running these survival schools are seeing an influx in regular people who want to gain these skills," Snyder said. "It's really a form of insurance."
Tom Brown, Jr., founder of the Manahawkin, N.J.-based Tracker School, is one beneficiary of this influx. Brown said his wilderness survival school, in operation for 37 years, instructs about 2,000 students annually, many of whom are worried about potential economic disaster.
"A lot of my students, about a quarter of them, are interested in a U.S. government meltdown or financial crisis," said Brown. "They're starting to take that prudent look: What's going to happen tomorrow, what's going to happen five days from now, and how is that default really going to affect us?"
But it's not just survival schools that are seeing a government crisis-driven increase in business. Companies like MRE Star, an Arden, N.C.-based maker of pre-packaged "meals ready to eat," or MREs, are also getting a boost.
"Orders were fairly steady from January to three weeks ago," said company operations manager Ken Lester. "But the orders in September were double any month from January to August."
Lester said MRE Star, which ships thousands of cases of MREs each month to customers that include U.S. embassies abroad, is now seeing larger-sized retail orders from individuals, stemming from concerns surrounding the government shutdown and potential debt default.
"Individual retail orders have been significant in the sense that people are ordering more than a couple of cases. Instead of ordering single cases, which have 12 meals, they're ordering more than a couple days' worth of meals," said Lester. "What's trending is four to 10 cases of MREs."
