Why are most high income individuals male?

Most people who earn very high incomes are male. Why is this? Feminist blame "the patriarchy". But I blame young women.

"What am I doing wrong?
Okay, I'm tired of beating around the bush. I'm a beautiful (spectacularly beautiful) 25 year old girl. I'm articulate and classy. I'm not from New York . I'm looking to get married to a guy who makes at least half a million a year. I know how that sounds, but keep in mind that a million a year is middle class in New York City, so I don't think I'm overreaching at all.
Are there any guys who make 500K or more on this board? Any wives? Could you send me some tips? I dated a business man who makes average around 200 - 250. But that's where I seem to hit a roadblock. 250,000 won't get me to central park west."
