Large-scale immigration poses problems of its own. America is one of the rare examples of a country that has managed to use mass immigration to build a skilled labour force. But America is an open, multi-ethnic society with a long history of immigration and strong legal and political institutions. China has none of these features.

In the absence of predictable institutions, all areas of Chinese society have relied onguanxi, the web of connections that often has extended family relations at the centre. But what happens when there are fewer extended families? One result could be a move towards a more predictable legal system and (possibly) a more open political culture. And, as shifts in China’s economy lead to lower growth, Chinese leaders will have to make difficult spending choices; they will have to decide whether to buy “guns or walking sticks”.

China is not unique in facing these problems. All rich countries have rising pension costs. And China has some advantages in dealing with them, notably low tax rates (giving room for future increases) and low public expectations of welfare. Still, China is also unusual in two respects. It is much poorer than other ageing countries, and its demographic transition has been much more abrupt. It seems highly unlikely that China will be able to grow its way economically out of its population problems. Instead, those problems will weigh down its growth rate—to say nothing of the immense social challenges they will bring. China’s Achilles heel will not be fatal. But it will hobble the hero.
