Safe Inside Or Out In The Nuclear Wasteland

You want to have a little fun with your friends? And by fun I mean start more trouble than you thought you would or are really comfortable handling? You are? Good. Try this:
   When you're gathered around twenty or thirty people - friends, family, co-workers, what have you - get one other person and start playing a hypothetical 'what if' game. Or, as Einstein put it, ein Gedankenexperiment. What you'll do is assume that the world has been utterly destroyed in a nuclear holocaust except the building you're inside. Every door and window has been sealed, there is no way for any of the radiation to get you. You're all safe.
   However... there are not enough resources to keep everyone alive. So you and your friend have to make the tough decisions regarding who gets to stay safe inside and who gets shoved to almost certain death (or mutation) outside. And you can't do it in secret, you have to discuss this right out in front of everyone. If people ask why you're the ones making the decision just tell them because you thought of it first.
   A friend of mine and I did this years ago, between shifts at the Olive Garden. We had some time to kill and decided to rank everyone in sight according to their fitness to stay inside our non-nuclear safe zone. For a while there we had a Purgatory of an airlock, halfway between salvation and damnation, but we had to abandon that idea when the population inside the airlock was greater than that either in or out. Being that we were in our early 20's we kept a lot of the hot waitresses because we'd need breeding stock to repopulate the Earth when the time came, and we kept a few of the smart guys because they'd be fun company, and then most everybody else we shoved outside. We kept only one guy in the airlock, so he could run outside and repair the antenna when we needed him to.
   What for us was a way to kill ten minutes turned into a days-long back and forth, complete with negotiations and pleas and backstabbing mutterings. Our population grew from just those people we could see that afternoon to the entire population of the restaurant, cooks, bus boys, waiters, cashiers, bartenders, managers, regional mangers, absolutely everyone. People really got into it, with those we kept inside very proud and disdainful of those outside, and those outside eager to make their case as to why they should stay safe and become part of the 'in' crowd. Those we relegated to the wasteland eventually decided they were going to form a radioactive mutant army and come back to storm the restaurant and take it by force. Until we pointed out that, because they would be contaminated by radiation, if they did breach the walls they'd just be turning the last hope for non-mutant humans into more nuclear fallout. And then we told them their lack of foresight is what made us put them outside in the first place.
   It was a very telling exercise in human nature, one that took us entirely by surprise. Who knew that people would take it so seriously? And, you know, now that I'm thinking about it, if I'd been a little quicker on the uptake back then that whole business probably could have gotten me laid.
   Ah well, live and learn.
