> People deciding to have or not have kids is a conscious decision based on their life experiences.
You're just looking at those who don't have children at all vs those who do, but that's not the whole story.
People don't decide these things in a vacuum - all over the western world statistics show that people have on average one child less than desired - mostly due to external pressures like availability of real estate and/or stable employment.
The environment simply doesn't support having more children, so those who do have them don't allow themselves to have more - much like animals which don't breed in captivity.
Countries like France largely staved off population decline because they decided to create an environment where people can have children as they naturally would.
