Age of Leisure - the post-war prosperity of the "Roaring Twenties" created a new consumer culture in the cities of Europe and America, allowing more fortunate people to indulge in various forms of entertainment
The 1920s were an age of dramatic social and political change. More and more people in Europe and America moved to cities, and the global economy was booming. A new class of people arose, swept along by economic progress and liberalization of social morals into an unfamiliar “consumer society", where leisure time was valued. People spent time engaging with all sorts of entertainment: from music, dancing, theatre, radio, film, to sports and recreation. Many were uncomfortable with this new, urban, sometimes racy “mass culture;” and many more were left behind, still trapped in poverty or on the periphery of society. However, for a small handful of young people in the big cities, the 1920s were roaring indeed, and the good times rolled.
