I see it from the complete opposite direction. What is wrong with the world and humans is all the generational trauma and how we used to raise and treat children.

So in my view the only way to heal the world is through children which are raised from parents who ideally have already worked on their trauma to be strong and caring individuals and learned to handle their emotions without supressing them.

Of course the political system is important too, but the thing is you need strong individuals first. If you have a population of people which have had their individuality "beaten out" and are slaves to their emotions they will inevitable seek comfort in groups and leaders leading to authorian regimes and fascism.

You can't change adults much. Every change has to come through our children.

I don't get having kids before making the world at least a decent place.

That seems like a very tall order for a single generation, and for such a large area (worldwide).

If everyone thought this way, we'd probably be extinct by now — or at least massively declining in places where birth control and abortions are widely accessible, since every birth would be an accident.

(To be clear, I can understand why one might not want to bring kids into the world in its current state. It doesn't seem unreasonable)
