Disasters do promote more pro-social behaviours, and more personal, non-bureaucratic interactions between people (it also promotes more people “acting cooperatively”, but actual cooperation seems much more efficient with laws and markets than with good will). But it’s precisely that that also promotes corruption and nepotism. Running more informal organisation is almost all about personal politics. And cooperation within the tribe often goes along with antagonism towards the outside.
