Utah: That one parable would save a LOT of grief if everyone took it to heart. Every "That's not fair!" issue would evaporate.
I'm reminded of a guy that used to work with my uncle. This guy was always tracking the bonuses, raises and promotions everyone around him got, always concerned about whether he was getting a fair deal relative to everyone else who worked there. So... sometimes they would make a point of talking about whatever bonus they got (or sometimes didn't really get, but they talked it up anyway
) in front of him, just to tear him up.
