I'm astonished at how sensitive the mods must be over there.
Apparently you're allowed to say whatever baseless slander you like about the eeeeevil tankies but the minute someone says "Hold up a sec, you claim to be anti-authoritarian and yet you support authoritarianism either explicitly or implicitly?" and they have to shut it down immediately.
Regardless, I think I made a pretty solid counterargument to the typical complaint about communism being authoritarian.
Mfers skim read the Wikipedia entry on Hannah Arendt and start thinking they're justified in slinging accusations about "muh authoritarianism" smh.
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.
Also more people means the diferens between mpl and averagepl is greater. And it can be argued that the ease of explotation of the workforce is proportional to that.
