It's not about marrying more attractive spouses for breeding better looking offspring, but what a lot of these studies miss is that wealthy people who are genetically disadvantaged have the funds the invest in their appearance to become better looking: best timely medical care, fixing teeth, becoming taller, correcting posture, hair implants, plastic surgery and skin care, hiring professional trainers and nutritionists, living in nice, quiet, green areas to reduce stress and sleep better, and other potential quackery rich people have access too like blood transfusions.
Just look at Jeff Bezos and Elon Musk before and after they became wealthy, they're better looking despite being 10-20 years older.
Basically, higher IQ can help you build wealth, and higher wealth can help you become better looking, but high IQ is not directly responsible for better looks.
