In the end it will not be "preps" that allow people to survive but skills, knowledge and adaptability. The old proverb about giving a man a fish vs. teaching a man to fish hasn't stuck around so long just because it sounds nice. People who can grow food, raise livestock, hunt, fish, trap, build, fabricate and those who have herbal and medical skills will do well. Those who know how to can, cook, sew, quilt, crochet and knit in addition will do even better. All are arts lost to most of the younger generations. I worry for the young people that never had to wash used tinfoil for their grannies, hoe the garden, gather fresh eggs, pick poke out of the swamp or hang out hand scrubbed laundry on a clothesline.
As an American it's your responsibility to have your own strategic duck stockpile. You can't expect the government to do it for you.
