Is retirement obsolete The 20th century could be called the “age of retirement” After World War II, there was a consistent decline in labor force participation with advancing age in all industrialized countries. For society, the decline in labor force participation represents a loss of productivity by older people, for several reasons: People are now living longer, People are better educated, and People are in better health than ever before History of Retirement: Widespread retirement by workers only became possible after the industrial revolution of the 19th century. Prussian Chancellor Otto von Bismarck first introduced the age of 65 as the basis for pension (European countries still refer to retirees as “pensioners”). According to statistics: The overwhelming majority of both men and women are retired from the labor force after the age of 65. Older men tend to move away from work and toward retirement. However, in 2000, labor force participation for people over age 65 was higher than it had been at any time since 1979, and the trend has continued into the 21st century.
