A pathetic condition/policy where there's only room for one Black person to shine in (at least the mainstream of) a given industry or
scene, even when there are many other talented and worthy Black
people to give
work or accolades to. Unfortunately usually those other
Black persons (as well as Asian, Latino, etc.) are snubbed or overlooked in favor of the anointed Black talent and/or a whole bunch of mediocre whites.
Oftentimes even that particular one Black
will see to it no one else benefits from the perks they
get, out of feeling those others are a threat to take their position.
Not to necessarily be related to affirmative action, though it kinda can be. And while not necessarily tokenism, one nigga syndrome is also in effect when whites
will bring aboard one Black person into the group and cap it there so that in case he gets out of hand, he won't have backup when they collude against him.
