Since Gates has some relevance right now:

"Nigerian-born Obianuju Ekeocha, author of the new book Target Africa: Ideological Neo-Colonialism of the Twenty-first Century, wrote an open letter to Melinda Gates, whose foundation dedicates impressive resources to spreading birth control among Africans: “I see this $4.6 billion buying us misery. I see it buying us unfaithful husbands. I see it buying us streets devoid of the innocent chatter of children. . . . I see it buying us a retirement without the tender loving care of our children.”

Africans are not the only intended beneficiaries of campaigns to expand the contraceptive Weltanschauung. Nor are they alone in abjuring the idea that the world would be better off with fewer of them in it. As one notable Indian targeted with the same message some years back put it, “It is futile to hope that the use of contraceptives will be restricted to the mere regulation of progeny. There is hope for a decent life only so long as the sexual act is definitely related to the conception of precious life.” The author of these sentences is not Elizabeth Anscombe, whose famous 1972 essay “Contraception and Chastity” defended Humanae Vitae with this same logic. It is instead Mahatma Gandhi—one more non-Catholic to affirm the reasoning behind Christian moral teaching. “I urge the advocates of artificial methods to consider the consequences,” he explained elsewhere. “Any large use of the methods is likely to result in the dissolution of the marriage bond and in free love.” "
