Your article is behind a paywall. My point remains the same: most rich men marry women less rich than them. Men marrying richer women are rare. You'll find more men married to women less rich than them than the opposite.
You won't marry up because women do not marry down, except when they are settling down. The type of women you're dreaming of (the money maker type) don't marry down or equal. They have the same mentality as you, especially when they are beautiful. They want to use their beauy to climb the ladder, not to help you climb.
In most cases, if she marries down or equal, it just means she's settling down or marrying a gigolo. So she'll be frustrated.
Once again, for a Rothchild, a doctor is a bum too. LOL. If you're a multi-billionaire, marrying a doctor or a waitress is the same thing financially: to you, they are both bums. A multi -millionnaire or billionnaire is not marrying a doctor for her bag.
So yes, if Im' in that position, I'll take that beautiful waitress over an average doctor. Why? In both cases they are bums to you and you'll be saving the two of them.
