This is something that Elizabeth Warren and her daughter Amelia covered in their book "The Two Income Trap." I'm aware that recommending a book by a political figure is fraught, but I'm not aware of any economists who took umbrage with the claim, either. They make the observation in chapter 1 that "Even as millions of mothers marched into the workforce, savings declined, and not, as we will show, because families were frittering away their paychecks on toys for themselves or their children. Instead, families were swept up in a bidding war, competing furiously with one another for their most important possession: a house in a decent school district."
Housing is a great way to establish a level of security for your family and kids; but there's a finite number of houses with proximity to good schools, jobs, and other necessary resources, and so families needed to dedicate larger and larger portions of their income to compete against other dual-income families that were bringing new money to the housing market.
