My dad works in public health, including in Bangladesh, I’m well aware of the issues. (That said, I think the anti-natalism of the international development field is under appreciated as a double-edged sword, as countries like South Korea and Singapore are beginning to find out.)
My point isn’t in disagreement with yours. Of course being poor is worse than being richer. My point is that even in Bangladesh, the level of prosperity is sufficient to exceed the threshold for humans to find life “worthwhile.”
