Capitalist society: Don't have a baby unless you're financially able.
Also capitalist society: You want a liveable income so you can afford kids? Lol, no.
Capitalist society, yet again: Why aren't you having babies? We need you to produce the next generation of labour, please.
I don't want to interrupt this nice tribal "capitalism vs unicorns" rant, but...
Decline in demographic growth is primarily a threat for social pension systems, where generation n pays pension for generation n-1 from their employment taxes.
If you had 10 employee contributing to 1 person's pensions say 50 years ago, and in 50 years it's going to be 1 employee, you can imagine it won't work.
@kravietz Any alternative is a unicorn, I take it?
Anyway, sure, that's also a threat. I'm not exactly sure what your point is, though, in the context of what I've said.
Today USA, Russia, Sweden and China are technically capitalist, yet they are extremely different in various social indicators.
You can't simply describe an extremely complex system such as each of these countries with a single binary parameter: "capitalist" or "non-capitalist".
@kravietz "Today USA, Russia, Sweden and China are technically capitalist, yet they are extremely different in various social indicators."
Agreed.
