After a gathering I walked out with someone who was annoyed by something and remarked that people needed more birth control. He was on an anti-child tiff. It happens. I get annoyed with other people's children, but I haven't lately wished for their non-creation. I countered, but honestly not looking for a fight, that it is better to grow your citizenry domestically lest you have to import them.
But anyway, even if you gave birth control away for free, introduced it to middle schoolers you'll still have people having kids, and I'm sorry you'll still need to pay taxes for schools. People in general and poor people are going to have kids. It's a part of life. The sex ed may curb the under aged pregnancy, but teens aren't your only broke people having kids. Looking at the CDC's data sheet on pregnancies, and remembering the book "Promises I Can Keep" about low-income unwed mothers, the bulk of births seem to come from ages 18 and up. I'm avoiding the "teenage" label because 18 and 19 year olds are teens, teens who can vote and sign legal contracts. Of the unwed teenage pregnancies, roughly 2/3rds of them are 18 and 19. Of all the unwed pregnancies, the 20-24 years olds have everyone beat. The 25-29 year olds are kind of equal with the under 20s. The smallest unwed group is the under 15 crowd, with 6 thousand births, trailing behind the next lowest group 40-54 year old women at over 21 thousand unwed births. Pregnant 15 years olds bad, pregnant 40somethings.... so what's the story there?
So your problem, if unwed pregnancies are a problem, I'm going to leave that judgment aside for the mo, ya got to get after the 20-24 yr old women. You figure at that age they are perfectly aware of birth control and how babies come into the world. My sister got pregnant in her twenties, I believe she was aware of birth control. It's that regularly taking it everyday part of the birth control that screws that up. And condoms.... ha. There is something that happens in a relationship where the condom is a symbol of something, dirtiness, distrust, prostitution, and the like. In the book Tally's Corner, about street corner men in the DC Shaw neighborhood, men would not wear a condom with a girl/woman they considered 'nice'. There is also another thing that I seem to see between the lines of these studies involving poor women and childbirth, despite being a bad marriage candidate the women seem to want some lasting connection with the guy and being his baby-momma makes that connection permanent.
What exactly can you tell a 20 or 24 year old woman not to get pregnant if she's unmarried? Well, besides arguing moral reasons that sex should be saved for marriage or stuff like that. Staying school? At 20 high school should be in the past and it would only appeal to those in college already, but then what percentage of women 20-24 are in college. Really at 20 if you're not already in college what is your motivation to start now?
In Promises I Can Keep, it was having the kid that provided the motivation to go to school or get a job or better job. I can see that with Sis. Okay she was not completely responsible after the first, or third kid, but she became more responsible with the kids than prior to their being.
