It's not that extreme, and I mainly just it as an example because it's something I've seen often enough for a variety of reasons (religion, Gov't cheques, etc).
That said, stuff like Elon and his quest to artificially impregnate at many women as possible with his progeny is just as messed up.
For those of us that aren't crazy rich arseholes, having one's first kid is often a trade off between an age when financial security is more likely, of prime birth/parenting years when one has a lower chance of complications/defects/etc, and then the issue of age gap between offspring after.
