Richer countries are rapidly ageing and productivity is stagnating. Meanwhile, industry - the motor for rapid economic development in the past - employs ever fewer people worldwide.

A rising, increasingly educated working age population in lower income economies can provide them.

In the future, it can foster the expansion of expatriate employment through skills partnerships.
