The document discusses factors that have contributed and may continue to contribute to changes in leisure time. It explores how leisure time exploded in the 20th century due to a smaller work week and larger leisure class. However, leisure time has declined since 1980 due to factors like married couples and children working more and longer work weeks. The document also examines trends that may cause leisure time to increase like technology and retired baby boomers, or decrease like limitless materialism and more service jobs requiring evening and weekend work.
