I mean I'm about a billion dollars short of being a billionaire, and I don't know how to live without exploiting labor either. I can't farm, I can't hunt, I can't identify edible berries, roots, and mushrooms, I can't sew beyond fixing a button. I know a lot about mechanisms, but it's far from clear to me I could do anything useful in that field once the electricity is out, let alone once source metal starts getting hard to find. Everything would get so much harder so quickly. Hell, I don't even know how to dig a latrine that'll prevent the water supply from being contaminated, assuming we can find a water supply. (On the plus side, sources of pollution in water supplies should start to fall apart pretty fast.)

I dunno. I just think everyone thinking about the collapse wildly underestimates how hard everything will be. I can't really picture my sorry ass lasting long at all.
