Important reminder: No one "owes" anyone children. You don't owe your parents, you don't owe your grandparents, you don't owe your deacon, nor your cult leader, and sure as shit not your country.
This is the fucking truth. It is also a very easy solution, most people want children, it is baked into our genes. It is just when the countries of the world have made the rules like they are now. That encourages ans premieres the hoarding of wealth into the hands of very VERY few. At the expence of exploiting everyone else and the planet.
It makes human civilization a dystopia not worth saving, and not wanting to put children thru this meat grinder, in order to enrich some asshole, is very normal and compassionate.
Make rules that are fair, and protects the planet. at the expence of some billionares having to be millioneres. And I bet most people would love to have children.
No amount of weaseling, manipulation, what-ifs, or post-hoc rationalizations change the fact that someone else's decision whether or not to reproduce is not yours.
Yes, it would be crazy if civilizations always fell due to collapsing because the people, like myself, deciding it's not worth producing children into this hell-world.
