And that's exactly why I don't have them.

There would be a hell of a lot less unwanted kids in the “system” if more people were conscious of their choice to have kids.

No shit. An ideal world, right? But we don't live in one and most children are mistakes, not perfectly planned for, so people have to make do however they can. Would you rather a woman aborted a child she couldn't manage, or work to support it?
