As an ex-resident, I'll admit to a certain level of bias
That said
at thinking china has some kind of unique demographic problem (Like all other first world countries that have this problem).
On the contrary, that is solid evidence they made the giant leap mao planned, even if it Deng Xiaoping actually took it, in a way quite contrary to what mao actually planned. China depends on US sales like everyone else does, including the US, you ers account for half of global consumption, more if you remove basic needs.
Bottom line is the chinese played the game better than anyone else. They sold cheap labor for know-how, and multinational corporations lined up equipping and training china to become the world's manufacturing center. China coupled that with education and long term planning, a recession hurts china but it also hurts everyone else.. I don't care for the authoritarianism (even when I don't find it to be more than the wests) but the long term planning is something I can only wish would reach capitalist societies like my own and yours...
