alt Hacker NewsA single income family in US with the husband working at a factory in fifties and sixties could afford a home with washing machine, dish washer, TV and a phone. Surely the home was smaller, but it was easier to clean, the TV screen was tiny, but then the family can go to a cinema. There was no internet, but for information one could go to the library. So how it was far below what people in US could accept today?
There are certainly a few people that would accept it, look at the whole "tiny home" and "van life" phenomena. It's possible that more would, if smaller houses were available. Builders make much more profit on larger houses though.
I guess apartment living is closer to what people had post-war, but everybody wants to buy a house to get in the real estate gravy train.
