Sorry, but this is a fiat mindset. Birth rates only matter if we want infinite growth, which is what the fiat system requires to pay for all the debt its accumulated. I'm not saying increased birthrates are bad or that the world needs to shrink in population. I'm saying that the increase or decline in population only matters to the elites and the average person shouldn't worry about it as long as they have enough to survive and thrive. If you want to have children and feel you can afford it, by all means have some, just don't buy into the propaganda that it's necessary for our growth as a species. It's not like we are at risk of dying out from not enough babies.
