Australia had a huge sustained boom from the late 1940s through to 1970s, which was also aided by the Korean war. The boom tapered off with the oil shocks and stagflation of the early-to-mid 1970s

The UK also had a boom, recovering from rationing into the 1950s they joined the global long boom until the 1970s but yes it was not as strong as other countries booms due to the damage and cost of the war

Harold Macmillan's famous 1957 line "you've never had it so good" sums it up pretty well

Europe had a massive boom known as the golden age of capitalism, nfi what you are talking about
