Plenty of assholes everywhere, though. It's not about a moral compass.
That's another weird one, I guess. You get this notion that suggests that rural settings somehow have the moral high ground or something. They don't. Sharing and community building are survival strategies. You help with gathering because you need help with gathering. You drop off the excess fish because at some point something needs to make up for your lack of lemons.
Going into a mad max rampage the moment the lights go off isn't being mean, it's being suicidal.
