原文

And the fact that today countries with higher fertility rates are poorer doesn’t tell us that they are poorer because of high fertility: It could instead be that they have high fertility because they are poor, or some third factor could cause both high fertility and poverty.

译文:

现在,很多更能生的国家更贫穷,并不能证明,他们更能生导致了更贫穷。也可能,他们更能生是因为更贫穷,或者他们更能生更贫穷是另有苦衷。
