Alienation of workers from their production. Commodification of housing, dating, etc. Growth without limits. These are factors that effect reproductive rates from a capitalist framework.Aging population problems dont exist because of capitalism.
State capitalism is no better, I mean war massively bumps fertility but that doesn't mean it's good.
The problem with an aging population is that more of the workforce needs to be involved in elder care? Is this really a problem
Pre bronze age? IDK kinda seems like this is a problem capitalism itself has created so to say it solves it better is silly, better than china? We'll see I guessCapitalism deals better with aging population then any other system.
But yeh there's bigger issues to worry about, low fertility is a good thing looking forward, less tragic deaths
