The bottom end of capitalism often looks quite like subsistence tribalism.

Well, yes. You can be sure that everyone outside the disaster zone will be along to restore capitalism before they restore electricity. The disaster is temporary but the economic structure remains. It's not even clear that being homeless in NYC on your own is better than being homeless in the ruins of your community. It may be better to turn up to your non-functional workplace and keep your job than evacuate and lose it.

(I think well-off people underestimate how much ordinary capitalism looks like imminent disaster to people at the sharp end - it's no use if the stores are open and the hospitals working if you can't afford food or healthcare.)
