day no. 17,490: no fault divorce and no reason marriage

"The obvious effect of frivolous divorce will be frivolous marriage. If people can be separated for no reason they will feel it all the easier to be united for no reason. A man might quite clearly foresee that a sensual infatuation would be fleeting, and console himself with the knowledge that the connection could be equally fleeting." — G.K. Chesterton, The Superstition of Divorce

No fault divorce leads to no reason marriage. If there isn't real money on the table, people will risk more than normal because there are no serious consequences attached to it. In other words, the risk is nearly eliminated. No one has any fun playing poker for pieces of candy they don't care about. It may be one way to gamble without "gambling," but it isn't really poker if there isn't anything real at stake.

The same can be said for marriage. If the vows aren't real, the breaking of them isn't a big deal. If everyone knows that no one means it, it means less if they get tired of playing along later. 

If covenants can be dissolved willy nilly they will be entered into willy nilly. If promises can be broken without consequence, they will be made with more regularity. Why not? What's the worst that could happen? Such is the mindset of those who approach covenants lightly and the lay of the land is the worst that could happen: evil is rewarded as good and good is derided as evil.
