This is an answer to "Why in the hell are these people "producing" children, if they aren't 100% certain that they'll be able to support them for the years until they are old enough to stand on their own feet?"

No, lack of contraception is not the issue here either. What, do you think that because you have low monetary gain you are perpetually unhappy and would not want to have children? That all procreation coming the poorest are mistakes and accidents?

That's quite a nice bubble there. Sorry to burst it.

If two people love each other enough, they might want to have a child. Yes, even if the future is unclear. Yes, even if it means selling the car, taking the public transportation and working over time and having multiple jobs. Whether the situation is permanent or temporary is not even an issue here.
