Study: High post black women not marrying

Black women who make the big bucks can't find a man. This--from a study on high-achieving women of color--proves what you already know and have lived for years.
The study, presented by the American Sociological Society, says black women risk not having children, thus a depopulation because, well, as the study puts it they're not getting married because there is no "reliable partner" out there.
Now, I don't have a problem with studies if the numbers support what is being said, but no "reliable partners"? What's that supposed to mean?
Is the study saying that black men (the ones out there and available) arent' "reliable?"
This just in: Black men hit harder with unemployment

Black Man 2.0

We all know The Plight, a hellacious cycle of abandonment, baby-daddyism and hypermasculinity that plagues black men in the United States. But do you see the new black man? The well-dressed, well-groomed prototype that has quietly saturated the streets? Although I hate the word metrosexual, the new black man is almost, like, half-gay. His sensibilities are softer, his voice is still deep but the edge is not as blunt, although he can be fussy. He's just as comfortable shopping as a woman is; it's ... hard to define really. It's like a new species. Call him, BM2.
