Niglets raised by human surrogate parents sometimes abandon slum mentality and some do not. Recall how hard the entertainment/Jewsmedia pushes wigger culture in all their agitprop "entertainment." If the slum mentality is environmental, the 15% deficit in cranial capacity, and inescapable resultant 2 standard deviation deficit in cognitive ability remain. "Naturam expelles furca, tamen usque recurret."
What makes races distinct, of course, is their genomes, developed in isolation, in vastly different environments.
Also, could you explain what you mean by "a nonexistent problem?" The nigger problem is very real. Come to Detroit some time and stand on the corner of Six Mile and Livernois and observe for yourself--but you'd better have some bodyguards, because the Vice Lords will want that pretty white skin of yours, to make into a drum.
