I'm not saying that those women (or men) are stupid, I'm saying that they are brought up badly due to the neglect. You're taking so much 'choices' for granted when they are actually educated choices. For example, finances (how much will a kid cost? Bigger car? Food? Rent?), job security (are the parent(s) comfortable?), time constraints (do they have time to spend with them?). Ironically, they may end up neglecting their own children despite best intentions (eg Working overtime on minimum wage so the kid can get into college for example but the kid ends up a drug addict).
The way USA's poverty is a form of a Spartan kid's bath. Many will suffer, a few will make it through and be strong. All the more while other countries provide social programs (Social governments) or strong families (Communal communities) to make it easier and more aware of the responsibilities of having a kid.
Throw into that mix 'abstinence-only' sex education, and your 'choices' disappear. If you don't know about protected sex, and it's clear that all this "choice" you mention is just illusion for a great many people.
You can't say "why didn't you use a condom?" if you block the information about condom use. Hell, in some parts of Africa, the Catholic Church is spreading information that condoms cause AIDS. Where's the choice there? Where is the 'luxury' there?
By the way, I didn't say the sex was the luxury, I said your stance was the luxury - this expectation that kids come along when you plan them. If you actually speak to parents, you'll find that kids frequently come along despite using high-reliability birth control, and sometimes never come along despite desperately trying for years.
What really is beyond ridiculous is your cold, calculating opinion of how humans operate, combined with this expectation that all humans have access to the information you have.
