An "older" world needs some policy changes
In short, the idea of retirement needs to be "retired"
As long as people are productive, they should contribute to society

The Age of Aging: How Demographics are Changing the Global Economy and Our World,
by George Magnus
"This book falls firmly into the last category. It provides a clear, sober and well-written analysis of the problem, both in developed and developing countries, and runs through the options for heading off the worst effects. The biggest part of the solution lies in expanding the shrinking band of workers, mainly by getting people to retire later and persuading even more women to take up paid employment. At the same time more productivity will have to be squeezed out of the labour force that remains. And people will have to be persuaded to save a lot more for their old age."
