Why do so many Haitian women not use contraception? My guess is because they don’t want to. The more kids they have, the more likely they might have somebody interested in taking care of them in old age, is perhaps their reasoning.
When population increases, and food supply does not, eventually it will result in having to kill your competitors over access to food.
The poorer you are, the less you can afford NOT to have children.
Nobody else will care for you in the midst of earthquake, hurricane, fire or natural disaster, or when you're unemployed, sick, disabled, or well on in years.
If people had a better prospect for the future with fewer kids, I double-dog guarantee they would know or find out how to have fewer kids.
I think your conjecture is entirely accurate. Furthermore, in large swaths of Haitian, oh, society, the concept of family, as we have traditionally understood it, does not exist.
To add my own guesswork, if one of my two children had disappeared as infants or toddlers, the alarm would have circled the globe because I would never have stopped screaming about it. Yet, with the Haitian children spirited away by Hillary's people, we only heard about them from a whispering campaign. Is it possible these children were voluntarily sold or traded by their mothers? Talk about having children for financial security! That's giving birth to your own meal ticket.
At any rate, the best form of contraception is a family that will be saddled with your mistakes; take money, food aid and every other reward out of bastardy and it will diminish to a manageable level.
