I think that's exaggerating a bit.
I go to a PWI. I don't know the ratio of black men to black women here, but there are PLENTY of black male students at my school. And although bw outnumber them, there are also plenty of eligible bm bachelor's at HBCUs.
If you want to meet/date educated black men, you can find them. Go where they are. (You may have to move if you don't live in the right demographic area.)
They can easily be found at black events, black student union meetings, African student meetings, Caribbean student meetings, frat events, African-American courses, etc.
Now, if one only defines "educated" has having a post grad degree, pickings of black men will be slim. But not VERY slim. Join the black graduate student society. Join other professional black organizations, journalists, doctors, lawyers, engineers, business, etc.
If all else fails, find yourself an African.
PLENTY of them around (educated and black).
I'm starting to feel like many "educated" black men and women like to find any excuse possible not to date each other.
