I watch lots of 60's era movies, and that is the common understanding. The attractive smart lady with the good career will gladly give that up to raise the children that are always conceived very quickly.
Yes -- and usually it was assumed that women were only using their careers as a means toward the end of meeting/attracting prospective husbands. E.g. you became a nurse in hopes of snagging a doctor as a husband, became a secretary to snag an executive, etc.
And you went to college to get your "Mrs." degree.
