Yeah, I can see room for disagreement in the first point. But being poor in a third world country is always a bottleneck situation. Being poor myself, I tell you I can't have kids because I don't have any wealth (because almost everything goes to socialists and the rent seekers that applaud them). Having a kid in my current situation would be an irresponsibility. When you are dominated by fiat and civil law, you are basically a vassal and everything around you is constantly depleted, eroded and poisoned. In USA, a lot of people were angry because the east palestine incident, but that kinds of events are experienced on a daily basis in my country. Hyperinflation sort of corrects slightly these problems because the governments can't squeeze us so easily but doesn't mean that this is a mechanism to foster procreation because it's unethical, fiat and completely wrong. It's the equivalent of Thanos but for human beings as a sort of resource, used basically to make proxy wars in a controlled way, not for exponential reproduction.

Even more, poor countries having more kids than rich countries is not a black and white situation. If you go to a country that have suffered hyperinflation like Japan, you will see that its population has the lowest birth rates, different from Russia in which men trade with a lot less life expectancy.
