Yep, the strategy of a small percentage of 20-something year old women is called, "the starter marriage." (Lots of videos about it by women advising other women)
Find someone with resources, divorce his rear after enough years, get half the assets and set up guaranteed income for quite some time. If there are children, then outrageous child support if the man is affluent. (Like $20,000 a month that Tom Cruise was paying)
From there she has her base of assets and income, and can then begin to set the bait for the next simp-sucker. Family law rewards this behavior, and the statues are certainly stacked in one direction.
But hey--don't pay any attention to someone recently divorced.
