The rich get richer, and the poor get children. There's a book I read recently that I thought did a good job looking into the demographic and social shifts associated with women having high workforce participation. It's 'XX Factor' by Alison Wolf, in case you're interested. She gives a convincing tour of some thorough data, but also makes it into a manageable narrative. She also did a decent Podcast interview on Econtalk, if you want a short version.
