I can definitely see this being a problem, as having a nanny indicates a certain status, and MANY folks who have an embedded superiority complex over blacks, no matter where they are from, (ie poor ass eastern europe, Mexico, or the damn trailer parks of america), they will more than likely always assume that they are better regardless, or too good to watch black children.
How many of these nannies have had bad experiences with WHITE families, but choose to continue working for another white family because of the "prestige?"
You're simply not going to get me to believe that ALL these black families are low paying and treating the nannies like shit, while the white families treat them like gold. The story is saying that the nannies are getting pissed at the agencies for sending them to a black family in the first place. If black families are having trouble hiring nannies in the first place (one family has been looking for 5 years), and nannies are refusing to work for black families because it's not prestigious, how could the nannies have experienced poor treatment, low pay and uppity employers when they won't work for the blacks in the first place?
It reminds them (The Nannies) of their shortcomings to see successful black people. They'd rather work for a white family because they expect white people to be something better, but they're jealous and envious of an upper-class black family doing the same thing.
About Black folks working for other Black folks as nannies... Pride has something to do with it, especially with the younger nannies. Somehow it makes them feel less than and even more worthless. This highlights how some blacks have been sub-consciously programmed into believing they are inferior and being that we are considered the lowest on the totem pole of race.
I don't care if you're a US citizen or immigrant, anybody knows if you can afford a nanny... You're not living in the ghetto, or an "unsafe" neighborhood. No one could make me believe that crap isn't an excuse for feeling inadequate when you see folks who look like you being able to afford to hire you.
