>[B]y far the most common reason given is that the cost of living has risen to such an extent that they feel that rearing children has become unaffordable.
That's certainly a factor, though very aggressive financial incentives for parents don't seem to work very well [0, 1, 2]. Not to mention that in rich countries, educational attainment and income are negatively correlated with fertility [3]. My theory there is that people's high-powered careers provide them more self-satisfaction than having kids.
>it's the fact that they can't even afford to buy somewhere to live.
It's funny you mention this. Some friends said they weren't having a second kid because they couldn't afford a three bedroom house, not realizing that kids sharing bedrooms was the norm for middle class families until very recently. Having one bedroom per kid was a luxury just 30-40 years ago.
>I won't comment on your assertion that the freedom to watch "adult-appropriate movies on a big TV in the living room" is a more fulfilling state of being than parenthood
It's not my assertion, it's something a couple deciding to not have another kid literally told me. They missed being able to have substantial amounts of adult time, and were actively counting down the days until their only child was old enough to amuse himself for long periods of time. Having another kid would reset that clock.
