Sorry I'm going to be contrarian here but if "people can't afford kids", then why is it well established that poorer people have more kids while richer have fewer? (https://en.wikipedia.org/wiki/Income_and_fertility).
Answering my own question.. I think the reason people are having fewer kids is more to do with urbanisation and all the social and cultural changes that come with that.
