Declining and ageing population in developed world vs increasing and younger population in developing world
Declining and ageing population in the developed world contrasts sharply with increasing and younger population in the developing world. There is a great synergy here. Developing world needs capital to fund education and developed world needs to save for the imminent retirement of their "boomers".
The twin objectives can be easily achieved if developing world allows private financing of education in return for share of their future earnings. Milton Friedman in the Capitalism and Freedom has also suggested that students should "sell" shares in their future earnings in return for finance for their education.
