If all black people left the world would be the same basically in terms of power and all that. Sports would suck, Music would suck outside of a few groups, and everything else they kind of picked up on so it would be here to stay. Everything is a system of checks and balances, they take us away and they just place, arabs, hispanics in our place.
Now take everyone away except white people and asians. Then the world is at its end.
