If the woman gets preg by a wealthy man, and hasn't signed a pre-nup---Hey she got wealthy. Don't sign one!
That is If she demands to HAVE the child! (my point here)
OK, I didn't see you were speaking from the viewpoint of a knocked up woman via a rich man. I took it as more general in nature.
Funny because I'm watching "An officer and a gentleman" , right now ( again).
The factory broads in this movie want to marry Navy pilots, as a way out....at least one of them.
Not that Navy pilots are wealthy, but way better than the lives these girls would live otherwise.
