Within a capitalist corporation, someone says, "Lend me a wrench," and someone asks, "Yeah, what do I get?" You assume that the idea of each according to his or her abilities, each according to his or her needs - in solving a problem - is actually the only thing that works. And in situations of disaster, there are often communistic notions of improvisation, where you basically exchange hierarchies and all of a sudden all those things that are luxuries that you can't afford, you have them in an emergency.
