Taking the social setting in to account that you described, I'm inclined to attribute it to that. Most poor people seem to lack any sense of responsability. They barely have money, yet they spend it on the newest cellphones or expensive clothes. They can hardly take care of themselves and yet they have kids in their late teens.
It just seems to be a culture of "no-responsability-makes-you-fit-in." This ties in with the fact mentioned earlier that a lot of those guys don't feel inclined to use condoms, because of all the hassle it brings with it, and probably also because it's un-male. A real, good, cool, man doesn't care about STD or pregnancies. He thinks he's immune to the first, or never heard of it, and pregnancies are the troubles of the women.
Apparently, a lot of those people simply have no idea about birth control. I saw a documentary where a 17 year old girl was convinced that you didn't get pregnant if you took a shower after the sex. Seriously, she hasn't given this any thought, has she?
This is all based on observation. (Some closer than I'd like.) I live in Belgium, so it certainly isn't a local problem, DW.
