Remember the scene in Charlie and the Chocolate Factory when folks were put on the scale and determined to be "GOOD EGG" or "BAD EGG" and the "BAD EGG" got flipped into some unknown oblivion so never got into the mix of life? A fantasy sure but a dam* good idea nevertheless.
So if we were born with GOOD EGG or BAD EGG engraved on an arm then we could separate all the bad eggs and ship them off to BAD EGG LAND and let them figger out how to survive one another thereby leaving the GOOD EGGS alone.
Farfetched? You betcha. But wouldn't YOU like to be able to avoid having to deal with BAD EGGS?
Unless you are one of course. But that's another story.
