The article discusses how older workers often leave the workforce instead of staying active, even though society is getting older. Younger workers also struggle to find the right jobs due to limited job mobility. The researchers suggest that making labor markets more flexible could help older workers stay employed. For example, offering flexible wages and hours could make it easier for older workers to find and keep jobs. This flexibility could not only benefit individual workers but also boost the economy as a whole by improving the allocation of labor and generating more wealth and growth.
