What would a 1970s single income lifestyle actually look like today?

Despite real wage growth, the consensus on reddit is that the economy was better in the 70s and a family could easily thrive on a single working man's income and build a house. What would such a lifestyle actually look like today? What things are better, which are worse? (I suspect almost only housing?). If you were to live a 1970s lifestyle, how much money would you have left compared to someone back then? A concrete "case study" calculation of the things that people spend money on back then in todays dollars is kinda what I'm looking for instead of abstract real wage statistics.
