A group of yeshiva kids I knew, when they flew overseas, they stole the inflatable vests under their airline seats and when they were in class in yeshiva, they’d pull the rip cords.
I couldn’t comprehend this type of carelessness with other people’s property and it bothered me because I liked these guys. We were in the same tribe. We were friends. We were part of a holy community. And for them, this theft was hilarious. They had no shame about what they had done.
This kind of carelessness with other people’s property seems to be a tribal thing. Every tribe has a tendency to be careless with other people’s property because every tribe practices a dual morality (one morality for how they treat insiders, another morality for how they treat outsiders).
