"The one-child policy drastically reshaped the composition of China's people. So now they have a population that's basically too old and too male and down the line, maybe too few. So the too old issue is that right now China has a dependency ratio of about five working adults to support one retiree. That's pretty good, that's a very healthy ratio. In about 20 years that's going to jump to about 1.6 working adults to support one retiree, and that's because that big population boom that we talked about, that big cohort of people are all living longer and getting older and therefore hitting their 70s, 80s and 90s, so by the time 2050 comes around one in four Chinese people will be a retiree."
