PCG, this isn’t fair. There’s no cause to single out Captain Obvious’ wife - you don’t know her or her circumstances and the comments you’ve made read like a personal attack.
Each person is entitled to marry who ever they want to: young, old, educated, minimally educated, rich, poor, attractive or not. It’s up to each couple to make their relationship work on whatever basis they choose.
What no one has a right to do is judge the 30 year old woman who chose to have a career, or the 30 year old guy who chose to marry the 20 year old girl. Each person made their own choice and it’s their responsibility to live with the upside and downside of that choice.
