I see plenty of one income families still. The problem people don't want to address in our society is that it wasn't much like this photo or the smoking idle housewives on Mad Men for many. Being the one home is a zero off hours job where the work is varied and difficult and requires much self management and discipline. Even today, those I know who do it and do it well spend countless hours finding ways to save money or make money at home. Gardening for extra food, having chickens or other small livestock to sell their products or lessen the grocery budget, finding creative ways like sewing or mending clothes and building things themselves. Selling things or dealing back and forth with neighbors for things in order to get what's needed without spending typical prices. Home schooling kids to ensure good education while avoiding private tuition. Usually even the working parent is called on to do more than a typical two income family after work to contribute to the self sufficiency of the family as far as extra building, making, tending, growing. This kind of work ethic is harder and harder to come by these days, not only because we live in Wall-E world, but because many of us are so much more physically afflicted by the toxicity of the world these days. It's a problem that compounds itself. The difficulty of it is part of why we have the world we do now. People loved government run schools because it gave them a lessened load at home. People appreciated mass manufactured processed foods for the same reason. Women were enticed away from home because it was easier, and none of us knew what we'd be missing until it was gone.
