Which phrase was used by economist John Kenneth Galbraith to describe the prosperity of the 1950s?

John Kenneth Galbraith used the phrase “affluent society” to describe the prosperity of the 1950s. The phrase became the title of his 1958 book, which examined the United States’ growing wealth and the uneven distribution of that prosperity. “Baby boom generation” refers to people born during the postwar birth-rate increase, not Galbraith’s description of the era’s prosperity.
