I admire the innovative thinking here, but I think some of the benefits of marriage as it currently is implemented have been swept under the rug. Ask yourself how many successful marriages are successful, in part, because dissolving a marriage is difficult and expensive. I’m not talking about people who choose to live in misery rather than divorce their partner. I’m talking about people who encountered difficulties that surely would have compelled someone in a two year contract to not re-up, but instead percervered because letting the marriage simply expire wasn’t an option, and working to improve the marriage was a more attractive path forward than divorce. You seem to think that the idea of a two year contract incentivizes greater performance without noting that the difficulty and expense of divorce already are their own incentive to work on your marriage. Again… I admire the innovation, but let’s be careful not to throw the baby out with the bath water.
