"People still have insane fertility rates in complete - objectively shitholes - like Bangladesh, etc."

Here is the fertility rate in Bangladesh: https://www.macrotrends.net/global-metrics/countries/bgd/ban...

I stand corrected, it doesn't have "insane fertility rate".

That's still a high fertility rate for a country with stats like this: https://www.globalhungerindex.org/bangladesh.html

> 25.1% of children under five are stunted, 10.7% of children under five are wasted

And the country had even higher fertility rates when it had higher frequency of famines, and much higher rates of hunger and malnourishment.

The point i was making however, is that parents don't truly - at a deeper level - consider the quality of life they are subjecting their child to.

Natural selection doesn't maximize for quality of life (it doesn't care for it), it selects for procreation and survival.
