Why did France introduce blacks?

1, because the fertility rate is extremely low. From a personal point of view, this is just a life choice, and there is no big problem, but from a national point of view, this is simply a huge disaster: the number of newborns is too small, the aging is intensifying, and future national taxation and conscription are problems. But the government must respect human rights and cannot force women to have children, so the only solution is to introduce immigrants.

2. Black labor is relatively cheap. For those black people from poor Africa, France is like heaven. Even if their salary is much lower than that of whites, they won't complain too much.
