I wonder whether it will catch on at all in this world where so many poor women are willing to serve as surrogate mothers, carrying to term the child of wealthier people even when the wealthy people are able to have a child in the normal way. If you’re rich, you can have a surrogate for not much more than the price of feeding and housing her for nine months. If she’s smart and you’re generous, you might also wind up agreeing to feed, house, and help educate her children. And you might give her husband a job.
