And digging deeper into that phenomenon is the mostly accurate sense that black people with 'black names' are far more likely to have been raised to distrust, resent, accuse white people, far more likely to have a huge chip on their shoulder, far more likely to dare anyone to discipline them or fire them less they be sued on civil right violations or something equally as silly. In other words likely to be a problem for the employer in various ways.
Of those black people who have become millionaires, the only ones who have 'black names' are all media/entertainment/professional athlete people. Those who make it in other professions pretty much all have ordinary American names, i.e. Robert, John, David, George or whatever.
The point of the story is that people who aspire to be ethically successful Americans do what all successful Americans do in order to become successful and that has nothing to do with race, ethnicity, or any other characteristic other than ability, aptitude, intelligence, ambition and work ethic. Those who teach kids to see their skin color as defining who they are and what they can aspire to will have seriously handicapped those kids.
Postscript: Asian people generally succeed and prosper more than any other demographic group because their parents encouraged/insisted that they do.
