Most people in a bad situation (e.g. financially) realize that having another kid rarely, if ever, improves it, hence it's not an intelligent thing to do. Furthermore, while bad luck can put anybody in a bad situation, intelligence is a major factor in getting out of it.
That said, "bad situation" is relative and we're far better off than people were historically, and high intelligence isn't strongly linked to genetics. Low intelligence can be, but higher intelligence is more a function of derived epigentic effects (thus a step or three away from direct natural selection) and upbringing (not the binary "good" or "bad", more how your environment affects you -- some people thrive in adversity and become dull with privilege).
