Different trends going in direction. There's a tendency for people with more simplistic viewpoints to see everything as a top down pyramid, where everything is mandated from elite bosses who gives orders down the line. It means everything is perfectly planned out. Meanwhile in reality, it's a chaotic system where everyone is attempting to achieve their self interest.
Here, once you become urbanized and educated, children become a cost rather than free labor. No one has a single solution to this, and immigration was meant to be a stop gap measure, where you fill in economic holes as needed. But then what happens if you have to replace what amounts to the entire population every few generations since the birth rates are below replacement?
What if every single country modernizes, and has dropping birth rates?
Where do the people come from?
NO ONE HAS ANY ANSWERS TO THIS since no one has thought this far along the system. The actors in the system are just trying to keep it going a few more years.
