Welcome, hillbilly chic. I think people that have had hard lives are the best prepared for any SHTF event. They already know how to do “possum living”. They know how to live cheaply or free. They can find a dozen uses for something a “richer” person would only see as garbage. They are tough as nails… and they’re realists.
For people out there that have never heard of “possum living”, please read Dolly Freed’s book Possum Living: How to Live Well Without a Job and (Almost) No Money. I learned a lot about cheap living from this book.
