Well... obviously life on another planet.
Firstly: I don't care if two people married out of some reason other than love and a mutual dependance.
Secondly: It doesn't neccesarily have to be because people love each other more. It could be because all people who are well versed in divorce cases suddenly have a heart attack, their head exploded, and they prolapse they entire digestive system all at the same time. Which would be something I'd want to see.
i'm not against marriage; it's a sentimental mile stone in many people's lives. I'm against people controlling each other with flimsy sheets of paper that basically say, "you owe me x amount of years of your life". And divorce rates going up would be a good thing, wouldn't it? People who are in love would stay married, and people who were in a loveless, fruitless and sexless marriage could peacefully seperate with much less a stigma and mess than, say, poking out each other's ear drums in their sleep and setting them on fire.
