It seems we were relatively richer then though. The Stockholm subway and train infrastructure, with hundreds of stations, was built in this period with miles and miles of tunnels, and several dozen underground station. Today we have to go trough hell and high water for a two station tunnel extension. My dad worked a builder, rebuilding the core of the city centre those days. The bonus from 2-3 months work bought him a new car. Try that today. It seems two to three decades after the second world war for countres that wasn't devastated by the war was a really strong growth period.
