Law that only favors women, of course. But that's perfectly fine. Let's make it so we have to pay Amazon to let us cancel Prime too. Oh, but that's different because Amazon is a faceless corporate and we haven't got blinders on when they're being evil.

Marriages should have a maximum term

Well, if you had to renew it every year, divorce wouldn't work anymore. You'd just have to pay off the other party an estimate of their expenses for the rest of the contract and you'd be free. It sounds like a far superior system to "I've been here 5 years slowly grinding him down to want to kill himself and now I want my cash and prizes.". It would put an effective cap on what they can gain from ripping people off. I would also suggest making divorce records public and searchable, so the serial divorcees get caught.
