however, you'd have to be willfully ignorant to deny the perceptual gap between high-end/low-end Emily/Amber vs. Lakisha
Oprah, Michael, Tiger, Sean, Robert, Mariah, Earvin, Jay, Bill, Sheila, Tyler, Shaquille, Dr, Master, Berry, Russell, Quintin, Beyonce, Prince.
The richest Americans are named:
Bill, Warren, Larry, Jeff, Charles, David, Mark, Michael, Jim, Larry, Sergey (immigrant, didn't change name), Alice (inherited), S. Robson (inherited) Christy (inherited), Sheldon, George, Phil, Forrest, Jacqueline, John, Steve, Carl.
Bill and Michael are on both those lists, but you would not say they are "black" names.
The thing is, there aren't a large group of upper class black people with different names from upper class white people, so you don't have an image in your mind of high-end black names. The rich and famous black people you know have either normal "white" names or very rare names (Beyonce, Prince, Tiger). High-end names default to looking white, since white is "normal" in USA.
The unfortunate implication of parent's statement is that there are no "high-end" black names, and therefore all 'black' names are low-end. Fuck, this is depressing.
