> Enter the Old Age Dependency Ratio: the ratio of economically inactive elderly people to the working age population. Calling this a loaded proxy understates things – at what point do we define an elderly population to be inactive, and how do we think about the working age population? This would probably not matter as much if we leveraged improved technology and productivity to reduce the need for human labor. Rather it seems industrial (technological) revolutions have increased the number of hours people need to work to survive: https://groups.csail.mit.edu/mac/users/rauch/worktime/hours_workweek.html https://groups.csail.mit.edu/mac/users/rauch/worktime/hours_... This has been coming back down in places like the USA since the late 1800s, but still, why do we all have to work so much to the point that we're starting to worry about "supporting an ageing, nonworking population?"
