well AgileMind, I also keep the facts of my own country in mind. fact is, over here, there are people who get a social house (so, basically paid by the community), who get wellfair, who refuse jobs when offered, yet do have some job(s) on the side which they don't declare.
saying that they are not educated in sex-ed .. well, no offence. that's just crock. by now they're smart enough to have figured out where the babies come from, and what condoms can do.
no, I'm not saying that they're all in that financial situation before getting pregnant, but ... again, a well known fact. there are enough couples (I don't assume America - or any other country, for that matter - is so different from here) who basically just keep getting children, because they get social benefits and childsupport for them.
yes, people live longer, but (again: looking at our own situation) if there were better and more effective controls on those abusing the system, thre would be a lot more money to provide for those who worked a full career, even for those who didn't.
