Leisure as a culture is not a universal societal value although the younger generation in developed or near-developed societies seems more inclined toward it. Overseas trips, lounging in a cafe with friends, attending concerts, relaxing in a spa, karaoke-ing and similar activities after office hours are now prevalent among that generation. In fact, over the last 15 years, the market has seen a tremendous surge in demand for such leisure services. In his book "In the Era of Human Capital", Richard Crawford charted the exponential growth of the Business & Leisure sector in the post-industrial society.
