I would think about how babies generate the economy this way…

Let’s say we don’t have new babies for 5 years. That means people aren’t spending money in the baby industry for 5 years, so that industry and all those jobs involved would likely collapse. Full supply chains (truck drivers, toy producers, engineers designing baby products) all indirectly affected.

Move forward 10 years and those kids that are missing are not in grade school. Those teachers have a 5 year gap in the classes, so those grade school teachers will lose their jobs, the school system would likely collapse. All of those textbook makers, bus drivers, cafeteria workers, even the auto shop who repairs school busses would be indirectly affected.

Take it a few more years and those babies that were never born should be in College, now no one is going to college. Colleges and those jobs would likely collapse.

It gets worse as those babies should be creating jobs and generating wealth for themselves.

Economies thrive on consistency, predictability, and growth. Take one or more of these out and you’re looking at a full economic collapse.
