> If you are not married and one partner makes significantly more than the other, what's to stop the wealthy partner just deciding 20 years into the relationship that they want a newer model and just leaving the former partner destitute?

So you like to force your spouse to stay in an otherwise unhappy marriage by putting a ring on their finger and have them sign a paper? So romantic!

Kidding aside, among the many reasons people like to marry, this is one of the worse ones.
