The Living Force
If things get that bad, having a 6-month supply of MREs won't do much good, even if you've got an AR to defend them with. The starving masses will certainly notice who isn't going hungry, and with an economic collapse of such a scale things will get extremely chaotic.
Not that one shouldn't take precautions ... Just, at that level of chaos, plans tend to go out the window.
A good network of mind-liked people may be able to defend themselves well. I think the first 6 months will be the most intense before peace and stability may return. Try to survive those together. Prepare for the worst, hope for the best. That's all we can make of it, I think.
