A single family home for everyone is unsustainable though, going back isn’t a bad thing and the family structure you’re talking about also existed because people had multiple generations under the same roof.
It can be since people now have the ability to choose to have kids. With pop decline equilibrium might be. Yeah not sure what the interpretation of family structure is but for me I think it is more that grand parents work now. So If I moved back home and had kids today both my grandmother and mother are still working to pay for the home I grew up in so who would help? When I was a child my great grandmother didn’t have a job and took care of me. Course my great grandma couldn’t read.
If your whole family lived together not everyone would need to work, food expenses would go up, but the mortgage wouldn’t.
And it’s still unsustainable from a climate change perspective, single family housing means more land use means more people need to drive to work.
I dk you are right mortgage going away Will help but taxes are just half monthly rent and houses need repair. I don’t feel the escape. My other side of family also lives in multi gen and with all the kids In college at the same time and covid killing half the working adults in the home my aunt had to take out a loan for emergency house repairs. It’s frustrating to watch. Plus my siblings only have rooms because people died.
Well with more remote work, less ppl drive to work so that may help or maybe improve mass transit.
