In my circle, I've seen it work, not in the same way though. Attractive women often go after the wealthiest men they can get. Likewise the minute a man goes out of a job, the strain in the marriage becomes immediate in a dual income household; less likely in households where the man was the sole breadwinner. The greater the difference in incomes and/or wealth, the more likely the marriage is going to last. And no, these aren't observations from some theocratic shithole in the Middle East or some ultra conservative Asian circles. These are from all the most liberal cities in the world.
And there is data to suggest children of high earners tend to be more attractive, for just this reason.
A woman who is a 9 out of 10, but not inclined or able to make her own high-earning career, can jump to the head of the income line by marrying a wealthy man. No one is surprised by this, but there are certainly some genetic consequences.
Of course, children of high-income families have better access to dental care, pimple medicine, and so forth, in the US.
