That question presupposes that the only people it is worthwhile to save from starvation is the one who grows up to make a large impact on their country. It's the sort of logic that I find very dangerous.
Let us say that you knew with absolute certainty that none of them would grow up to revolutionise their society. Would you still save them, or would you let them die?
It's a pointless question as it is absolutely impossible to predict. So we continue to attempt to save them all. They will make other contributions too, or their children.
