Marriage in the past was considered a fair deal because you got someone who would help out around the house, doing chores that would take hours if you did them yourself.

But now, I don't need someone to stay home and do that for me. I can set all the appliances on before I go to work, and even at current energy prices, it's still far, far cheaper than providing for a whole extra person. That's not counting the lack of stress caused because you don't have to worry about drama she causes.

The agreement has to be changed to acknowledge that men are the people losing out. You don't even have to go into what women are like as people to acknowledge that the deal is based on outdated logic that has long been supplanted by technology.
