I think this thinking tries to obscure an immense yearning that is buried within people who may want families, but do not feel it is realistic for them. I know this because I post a lot about my own children on twitter and some of the DMs I get are essentially confessions from men and women saying exactly that.

In survey data completed fertility is usually way lower than desired fertility, and even then on surveys we cannot expect people to necessarily say what they really want if they do not think it is achievable for them.
