Allianz: Government and companies must arbitrate between right to retire and right to work to compensate for the ageing of the workforce. With the exception of Africa, all regions of the world will see a slowdown in the growth of the working-age population.

A postponement of retirement to 68 would allow Europe to expand the working population by 6 million people, according to Allianz. Today, only one in two Europeans aged 60 to 64 is still working, says the study by the German insurer.
