It did exist, during establishment supported oppressive eras of America's history with lacking civil rights. To think it exists in today's age is quite nutty. Some people will bend over backwards trying to tell them selves that a person is somehow still befitting from some leg-up their great great great grand parents got during those times. Of course, that is far from realistic. I think the renewed concern may be a defensive action. When you no longer have anything holding you back, but don't feel you've achieved greatness, instead of wondering if you put in the effort, people tend to start looking for external things to blame for holding them back.
