Labor participation rates among women haven't changed drastically since the 80's. Also: https://economistwritingeveryday.com/2022/06/22/us-households-have-a-lot-more-income-than-1967-and-its-probably-not-just-because-of-the-rise-of-dual-income-households/ https://economistwritingeveryday.com/2022/06/22/us-household... > In fact, this is also a period when the number of two-income households shrunk, from 35% in 1987 to 32% in 2020.
