"Demographic timebomb" is 90% a capitalist dogwhistle to rob people out of retirement benefits and heap some more austerity like in France for example. In centrally planned socialist economy it won't be hard, and even the consequences of one child policy will be very possible to mitigate. Hell even capitalist countries don't collapse because of that, like Japan constantly whines about "demographic crisis" for 2 generations at this point.

The demographic timebomb is a threat to the profitability of capitalism, which is predicated on infinite growth. Fewer people means less labor to exploit and less consumers for products, both of which are devastating to the growth of profit.

A socialist society doesn't much care about profit or growth, so long as the working population can produce enough goods for everyone. China is one of the biggest producers and consumers of industrial automation and robotics, so its entirely possible that by the time the population starts shrinking overall or the working population ages into retirement the productivity of the remaining working population will be more than enough to sustain everyone.

Aside from how other people have responded to this, which is all really solid stuff, the "demographic timebomb" looks like... China having a median population age almost identical to that of Europe's by 2050.

How terrifying!

(Also note that the average age of Europe is skewed by certain countries having significantly younger or older populations, so what this will look like in 2050 for individual countries in Europe will be of more interest demographics-wise.)

I wonder if the libs are equally concerned about the "European demographic timebomb"? Maybe Gordon Chang can pivot and start writing about the coming collapse of Europe when his immanent-collapse-of-China grift collapses?

There are still 500 million rural chinise. So the loss of population in cities due to low fertility can be replaced by migration. This gives china a buffer so that they will a demografic crisis latter than even the us.
