I think you undersell how people lived in the 1950s.
I live in a house built in 1954 and it was originally about 1800 finished square feet with 3 bedrooms. Switching counter tops to Formica was probably an upgrade over previous choices which probably had been wood or linoleum. I don't think automatic dishwashers were that widespread until the 1960s or later.
But I think they would have had a washing machine, possibly a dryer, almost certainly a TV and a couple of radios.
I think in many ways the lifestyle of a 1955 family probably felt extremely futuristic to them -- for a lot of them, I bet they had first hand experience with houses without central heating, wood cooking stoves, using an outhouse, no automatic hot water heater.
The other high tech stuff nobody had, either, so they weren't exactly missing it.
