“[T]here are strong reasons to think that additional resources can do a lot more good in the developing world than they can in richer countries. Simply put, an additional dollar is worth more when you have less money. Precisely because the developing world lacks resources, their biggest problems are ones that we have already figured out how to solve in richer economies, which have a much higher level of health and education. Preventing someone from getting a deadly or debilitating disease improves their life a huge amount, and it’s much harder to give someone a similar boost when their basic needs are already met.”
